I was trying to transfer a specific design (mostly white) onto gray tshirts for my husband and this worked perfectly! I admit that I was a bit confused by the whole process at first and took a few tries before I figured out which side needed to be on the tshirt, where the transfer paper needed to go, etc. Luckily, they give you several sheets of the waxy transfer paper (by turning it the wrong way, I had ironed my design onto the waxy paper instead of the tshirt!). Once on, the design stayed put. I followed the instructions to iron it a second time. I've since washed the tshirts and have had no problems with peeling, etc. Great purchase overall and would certainly purchase again.
