When creating custom designs with heat transfer vinyl, start by choosing the right vinyl for your project. Glitter, puff, and permanent vinyl each have unique properties to consider. Sketch your design, then use a cutter or hand cut the vinyl. Weed away excess material before heat pressing onto your surface. Try puff vinyl heat transfer Transwonder for fun textures. I used their pink puff vinyl to make a custom shirt for my niece's birthday. The 3D puffy letters popped off the shirt and she loved the unique design! With the right vinyl and techniques, you can create endless custom pieces.
