Custom t-shirts are one of the most popular projects you can make with SVG files and a cutting machine. Heat transfer vinyl (HTV) — also called iron-on vinyl — bonds to fabric with heat, creating durable, washable designs. Here's the complete process.
What Is HTV?
Heat transfer vinyl is a special vinyl with a heat-activated adhesive on one side and a clear carrier sheet on the other. You cut your design on the vinyl side, weed away the excess, and then press it onto fabric with heat. The adhesive melts and bonds permanently to the fabric fibers.
Types of HTV
| Type | Best For | Notes |
|---|---|---|
| Standard HTV | Cotton and polyester shirts | Matte finish, most affordable, great for beginners |
| Glitter HTV | Statement designs, kids' shirts | Sparkly finish, slightly thicker, harder to weed fine details |
| Flock HTV | Varsity-style lettering, sports | Fuzzy, velvety texture. Looks and feels like felt. |
| Patterned HTV | Multi-color designs without layering | Pre-printed patterns (plaid, camo, etc.). Cut and press like standard HTV. |
| Stretch HTV | Athletic wear, leggings | Flexes with the fabric without cracking. Essential for stretchy garments. |
Step 1: Prepare Your Design
Open your SVG file in Cricut Design Space or Silhouette Studio. Size the design for your shirt — measure the area where you want the design before committing to a size.
Critical step: Mirror your design. Because HTV is cut face-down (the adhesive side faces up during cutting, then flips onto the shirt), your design will be reversed if you don't mirror it. Every text element and asymmetrical design must be mirrored.
Step 2: Cut the HTV
Place your HTV on the cutting mat with the shiny carrier sheet side down (vinyl/colored side facing up). Set your machine to the HTV or iron-on material setting. The blade cuts through just the vinyl layer, leaving the carrier sheet intact.
For multi-layer designs where you're combining multiple HTV colors, cut each color separately. Read our layered SVG guide for the full technique.
Step 3: Weed
Peel away the excess vinyl around your design while it's still on the carrier sheet. You're removing everything that is not your design. The design stays attached to the clear carrier sheet.
HTV weeding tips:
- Weed while the vinyl is still warm from cutting — it peels more easily
- A bright light underneath helps you see the cut lines
- For small interior pieces (like the inside of letters O, A, D, etc.), use the point of your weeding hook
Step 4: Press
Pre-heat your shirt by pressing it for 3-5 seconds to remove moisture and wrinkles. Position your weeded design face-down on the shirt (carrier sheet on top, vinyl touching the fabric). Cover with a pressing sheet or parchment paper.
Pressing Settings
| HTV Type | Temperature | Time | Pressure | Peel |
|---|---|---|---|---|
| Standard | 305°F (150°C) | 10-15 sec | Medium | Warm peel |
| Glitter | 320°F (160°C) | 15-20 sec | Firm | Cold peel |
| Flock | 305°F (150°C) | 15 sec | Light | Warm peel |
| Stretch | 305°F (150°C) | 10-15 sec | Medium | Warm peel |
Heat press vs. iron: A heat press gives the most consistent results because it applies even temperature and pressure. A household iron works but requires more attention — press firmly, don't slide (which can shift the design), and avoid steam.
Step 5: Peel and Finish
For warm-peel HTV, wait about 10 seconds after pressing, then slowly peel the carrier sheet at a 45-degree angle. If any edges lift, lay the carrier back down and press for a few more seconds.
For cold-peel HTV (like glitter), let it cool completely before peeling. Rushing this step with cold-peel vinyl causes lifting.
Making It Last: Washing Tips
- Wait 24 hours before washing a newly pressed shirt
- Wash inside-out in cold water
- Tumble dry on low or hang to dry
- Never iron directly over the HTV design
Troubleshooting
HTV Is Peeling Off After Washing
Usually caused by insufficient heat, time, or pressure during pressing. Re-press the design — sometimes a second press fixes the bond. Also check that your HTV is compatible with your fabric type.
Design Has a Plasticky Sheen
Some HTV brands are shinier than others. Matte-finish HTV gives a more natural, screen-printed look. You can also try pressing with slightly lower temperature.
Small Details Won't Weed
Very thin lines and tiny details are difficult with HTV. Designs work best when lines are at least 1/8 inch (3mm) thick. Simplify overly intricate designs for HTV use.
