What Can You Make?
Dye-Sublimation is a technique that transfers designs onto materials using heat and special sublimation ink. The heat allows the ink to bond with the fibers of the material, creating durable, vibrant designs that won’t crack, peel, or fade over time. Sublimation works best on synthetic fabrics or materials, especially those that contain at least 65% polyester. Here are some projects that showcase just a few possibilities:

How It Works
Prepare Your Design
Before printing, make sure your design is mirrored (flipped horizontally). Sublimation transfers are applied face-down, so mirroring ensures your image and text appear correctly once heat pressed onto the material.
Gather Materials
Sublimation works best on items made of at least 60% polyester or products that have a polyester coating. This process allows you to permanently transfer full-color designs onto a variety of blanks. Makers commonly sublimate onto items like t-shirts, mugs, and other specialty products.
