Free Resources
Guide

Before you open Illustrator for the first time, get your resources organized. This guide walks you through every free tool, site, and resource you need — bookmarked and ready before your first session. A few minutes of setup now saves hours of searching later.

Your First Assignment — Bookmark Everything
Create a folder in your browser called "Creative Resources." By the end of this guide, it should have bookmarks for stock photos, color tools, fonts, AI generation sites, and your print-on-demand platforms. Every chapter includes a bookmark assignment. Do not skip them — these are the sites you will return to on every single project.
What This Guide Covers
Stock Photos — Chapter 2
Free photography sites for reference images, subject matter research, and design inspiration. These are the images you will trace and reference in Illustrator. Quality reference = faster, better builds.
Color Tools — Chapter 3
Free color palette generators, harmony tools, and swatch extractors. Use these before opening Illustrator to plan your color story. A strong color palette is one of the biggest factors in whether a design sells.
Fonts — Chapter 4
Free font libraries for commercial use. Know where to find them, how to license them correctly, and what to look for when pairing fonts for t-shirt and apparel design.
AI Generation — Chapter 5
AI tools for generating line drawing references, concept images, and design inspiration. Includes the exact prompt formula that produces clean, traceable line drawings — not complex photos.
Print on Demand — Chapter 6
The platforms where your designs get printed and sold. Every platform has specific file requirements. Knowing them before you build saves you from exporting the wrong format at the end.
Rule of Thumb — Never Start from a Blank Artboard
Every design starts with a reference. A photo, a sketch, an AI-generated line drawing, or a traced image. Starting from a completely blank artboard without any reference is one of the most common reasons beginners get stuck. This guide gives you every tool you need to always have a starting point — before you open Illustrator.
Chapter 2 of 7

Stock Photos
& References

Stock photos are your raw material. You are not using them in your final design — you are tracing over them or using them as proportion and pose references. A clean, well-lit photo reference makes the difference between a tight, professional build and one that looks off.

What You Are Looking For — Not a Full-Color Photo
When searching for references, look for images with clean edges, strong silhouettes, and good separation between the subject and background. A photo on a white or plain background is ideal. Avoid complex, busy, or heavily shadowed images — they are difficult to trace and create a messy template layer. Simple = faster build.

How to Search Effectively
1
Search by Subject Matter + Pose
Be specific. "Golden retriever sitting side view" is better than "dog." The more specific your search, the more useful the reference. Think about the exact angle, action, and pose your design needs before searching.
Add "white background" or "isolated" to your search to find cleaner, easier-to-trace images.
2
Remove the Background Before Placing
Before placing any stock photo into Illustrator, remove the background first. Use Adobe Express (free), Canva Background Remover (free), or remove.bg (free). A clean subject on a transparent background creates a much cleaner template layer to trace from.
Adobe Express → Remove Background → export PNG → place into Illustrator
3
Save Multiple Options Before Building
Download 3–5 reference images for any project before opening Illustrator. You may decide to combine a pose from one image with proportions from another. Having options upfront prevents you from stopping mid-build to search for references.
Assignment — Stock Photo Bookmark & Search
Complete These Steps Before Moving On
1
Create a "Creative Resources" bookmark folder in your browser
2
Bookmark Unsplash, Pexels, Pixabay, and Adobe Stock
3
Go to Unsplash and search for the subject matter of your first design idea — save 3 images you like
4
Note which image has the cleanest background and clearest silhouette — that is your best reference
5
Bookmark remove.bg or Adobe Express for background removal
Think About This
What subject matter will your first design be? The clearer you are, the faster your search will go.
Is the image you found simple enough to trace? Complex backgrounds, harsh shadows, and busy scenes create difficult template layers.
Does the pose or angle match what you want the final design to look like? A side view, front view, and action pose all require different amounts of tracing work.

Color Tools
& Palettes

Color decisions made before you open Illustrator save enormous amounts of time during the build. A focused palette of 3–5 colors with a clear structure gives every design a professional, intentional look. These free tools make palette building fast and accurate.

Why Color Planning Comes First
The biggest color mistake beginners make is choosing colors while they are building. Switching between palette tools and Illustrator mid-build breaks concentration and leads to mismatched, inconsistent color choices. Plan your palette first. Lock it down. Then build with that palette and nothing else. Three to five colors is always enough for any apparel design.
Free Color Tools

How to Build a Palette Before You Build
1
Extract from Your Reference Photo
Go to Adobe Color > Extract Theme. Upload the reference photo you found in Chapter 2. Adobe Color pulls 5 dominant colors automatically. This gives you a palette that is already harmonious with your subject matter — the colors feel connected to the design because they came from it.
color.adobe.com → Extract Theme → upload photo → save palette
2
Limit Your Palette to 3–5 Colors
More colors do not make a better design — they make a harder one to print. POD platforms and screen printing work best with limited palettes. Pick one dominant color, one or two supporting colors, and one neutral (usually a dark or cream). That structure handles 90% of all apparel designs.
One dominant + one accent + one neutral = a complete apparel palette. You can always add a fourth for highlights.
3
Save Your Hex Values Before Building
Write down or copy the hex codes for your final palette before opening Illustrator. Keep them in a notes app or text file. You will be typing these values directly into Illustrator's color fields during the build — having them ready saves constant tab-switching.
Assignment — Build Your First Palette
Complete These Steps Before Moving On
1
Bookmark Adobe Color, Coolors, and ColorKit
2
Go to Adobe Color → Extract Theme and upload the reference photo from Chapter 2
3
Save the generated palette — note the 3 colors you would actually use in a design
4
Open Coolors and generate 3 new palettes by hitting spacebar — lock any color you like
5
Write down your final 3–5 hex codes somewhere you can access them when you open Illustrator
Think About This
What garment color will your design be printed on? Dark shirt vs. light shirt changes which palette colors will actually be visible.
Does your palette have enough contrast? Light colors on a light garment disappear. Dark colors on a dark garment disappear. Check your palette against the actual shirt color you are targeting.
What mood does your palette communicate? Earthy and muted feels vintage. Bright and saturated feels energetic. Does your palette match the vibe of your subject matter?

Fonts &
Typography

Typography is a design element on its own. The right font can carry a t-shirt design by itself. Know where to find fonts, how to license them correctly for commercial use, and what to look for when pairing two fonts for apparel work.

Licensing — Check Before You Use
Not all free fonts are free for commercial use. "Free for personal use" means you cannot use it on products you sell. Adobe Fonts and Google Fonts are safe for commercial use. DaFont requires you to check each font's individual license — look for "100% Free" or "Public Domain." Font Squirrel only hosts fonts cleared for commercial use. When in doubt, check the license page before using.
Free Font Resources
Adobe Fonts
fonts.adobe.com
Included with Creative Cloud. Thousands of professional typefaces — all licensed for commercial use. Activate fonts directly into Illustrator without downloading. The safest option for design work you will sell.

Font Pairing for Apparel Design
1
Display Font + Simple Supporting Font
For apparel, pair one strong display or slab serif font for the main headline with one clean, simple sans-serif for secondary text. The display font carries the personality. The supporting font provides structure. Never use two display fonts at the same weight — they compete.
Anton (headlines) + Montserrat (body) is the combination used throughout Jason's tools — clean, readable, and strong at any print size.
2
Check Readability at Small Sizes
A font that looks great at 72pt on screen may be completely unreadable when printed at 1-inch tall on a garment. Before committing to a font, test it at small sizes — 12–16pt in Illustrator — and check that all letterforms remain legible. Script and decorative fonts often fail this test.
3
Install Fonts Before Opening Illustrator
Install your downloaded fonts (Google Fonts, DaFont, Font Squirrel) at the system level before opening Illustrator. Illustrator reads fonts at launch — fonts installed while it is open may not appear until the application is restarted. Adobe Fonts activate instantly from within Illustrator.
Install font file → restart Illustrator → font appears in font list
Assignment — Build Your Font Collection
Complete These Steps Before Moving On
1
Bookmark Adobe Fonts, Google Fonts, DaFont, and Font Squirrel
2
Go to Google Fonts and filter by "Display" — find one strong headline font for your project
3
Find a second, simpler sans-serif font to pair with it
4
Download and install both fonts before your first Illustrator session
5
If using Adobe Fonts: activate your chosen fonts now in the Creative Cloud app
Think About This
What is the personality of your design? Vintage, bold, playful, or minimal? The font should reinforce that personality — not contradict it.
How much text will your design include? A single word headline needs a very different font than a four-line quote. Readability requirements change with text length.
Will the font be large or small on the garment? Small text needs clean, open letterforms. Large display text can handle more complex or decorative styles.

AI Generation
& Prompts

AI image generation tools can produce clean line drawing references in seconds. The key is knowing how to prompt for traceable results — not photorealistic images. One specific prompt formula consistently produces the kind of clean, simple line work that translates directly into vector building.

The AI Prompt Formula — Use This Exactly
"Create a line drawing of a [adjective] [subject matter] [action verb]. Basic shapes and lines only. Thin, clean black outlines. White fill. No shading. No textures. No background. No text."

The key words are: basic shapes and lines only and no shading. These two instructions eliminate the complexity that makes AI images difficult to trace. The result is a clean contour drawing — exactly what the Pen Tool and Pencil Tool workflows need.

Using AI Results — What to Do Next
1
Evaluate the Result — Is It Traceable?
A good AI line drawing reference has: clear, separated shapes with visible edges, minimal fill or shading, a plain white or transparent background, and proportions that match your design intent. If the result has gradients, heavy shadows, or complex overlapping shapes — regenerate with the same prompt before trying to trace it.
Generate 3–5 variations of the same prompt. Pick the cleanest one. You are not using the image — you are tracing its silhouette.
2
Save and Remove Background
Save the generated image as a PNG. Run it through Adobe Express or remove.bg to remove the background if needed. For a line drawing on white, the white background usually becomes transparent when placed in Illustrator at low opacity — but a clean transparent PNG is always better.
3
Image Trace as an Alternative
For a clean AI line drawing, Illustrator's Image Trace can convert it directly to vectors. Window > Image Trace. Use the "Black and White Logo" preset. Click Expand. Then Object > Path > Simplify to clean up anchor points. This is faster than tracing manually when the AI result is clean enough.
Place image → Window → Image Trace → Black & White Logo → Expand → Simplify

1
Bookmark Gemini, Nano Banana, Adobe Firefly, and ChatGPT
2
Open any AI tool and use the exact prompt formula with your subject matter filled in
3
Generate at least 3 variations — compare which has the cleanest, simplest line work
4
Save the best result as a PNG to your project folder
5
Compare it to the stock photo reference you found in Chapter 2 — which is cleaner and easier to trace?
Think About This
Is the AI result too detailed or too simple? The right level of detail depends on your build tool — Pen Tool handles more complexity than Shape Builder.
Does the AI image match your actual design vision, or just vaguely relate to it? Use it as a starting point — not a final direction.
Which reference would produce a better final design: the stock photo or the AI image? You can combine both — trace the AI silhouette, reference the photo for proportions.

Print on Demand
Platforms

Your platform choice determines your file requirements before you build anything. Each POD platform has specific size, resolution, color mode, and format requirements. Knowing these upfront means your artboard, color mode, and export format are already correct when you finish building.

Why Platform Choice Comes Before Building
The biggest time-wasting mistake in POD design is building at the wrong size for the wrong platform. Rebuilding or scaling a finished design because the export specs were wrong wastes hours. Five minutes reading your platform's requirements before opening Illustrator saves that time every single project.
Print on Demand Platforms

Universal File Requirements — Know These First
Format: PNG with Transparent Background
Almost every POD platform requires a PNG file with a transparent background — not a JPG. JPG does not support transparency. If you export as JPG, your design will have a white box behind it on the garment. Set your artboard up in RGB color mode and export as PNG every time.
Never export apparel designs as JPG. PNG with transparent background is the universal standard.
Standard Apparel Canvas: 4500 × 5400px at 300dpi
This dimension covers the full front or back print area for most apparel platforms. Building at this size ensures your design is large enough for any platform without upscaling (which causes blur). You can build at a smaller working size (like 360×360px) and scale up on export.
Apparel standard: 4500 × 5400px · 300dpi · sRGB · PNG · transparent
Color Mode: RGB (Not CMYK) for Most Platforms
Set your Illustrator document to RGB color mode for DTG and most POD platforms. CMYK is for traditional print — screen printing shops often request CMYK, but DTG platforms process files in sRGB. Set this when you create the file, not at export — changing color mode after building can shift your colors.
Assignment — Choose Your Platform
Complete These Steps Before Moving On
1
Bookmark your 2 primary POD platforms (Printful and Printify recommended to start)
2
Visit your platform's Help Center and find the file requirements page — bookmark it
3
Write down the required canvas size, DPI, color mode, and file format for your primary product (e.g. t-shirt front)
4
Create a free account on your chosen platform — explore the product catalog
5
Download a product template (Printful and Printify both offer free Photoshop/PNG templates) — save it to your project folder
Think About This
Where do you want to sell? Etsy + Printful for your own shop, or Redbubble/TeePublic for a marketplace with built-in traffic? Both are valid — your answer changes which platform you prioritize.
What product types are most important to you? T-shirts, hoodies, stickers, art prints? Different products have different file requirements — check before building.
What is your budget for test orders? Testing a physical print before listing is the only way to know if your colors and detail translate correctly. Budget for at least one test print of your first design.
