Primst Reflective Rainbow Heat Transfer Vinyl Roll 12inch X 5ft Iron on PU Transfer Vinyl DIY Heat Press Design for T-Shirt, Clothes, Hats and Other Textiles

I used this vinyl for a skating costume and it's worked really well. It did peel off a bit in some areas, but that's more down to the fact the fabric it was ironed onto is very stretchy. Nothing a bit of good contact adhesive wouldn't fix for problem areas like armpits and waistbands. On non stretch fabric it stays put. Really reflective when a light is pointed at it from the right angle, otherwise it looks dark grey. Not sure how it washes yet. Very easy to use, but the clear carrier film is pretty sticky and peeled off better hot. I got the best results by pressing on with an iron over a piece of cotton fabric and then carefully peeling off the film, and then pressing again to really make sure it's stuck properly as the film is thick and means it doesn't fully stick easily.

If it un rolls even a tiny bit the htv comes away from the transfer sheet and then needs to be messed with for sheds before cutting. I had to bin one project as I couldn’t get some of the air bubbles out and it made cut really bad :(
