I made my first shirts for our December trip. The design was perfect (Thanks to Kate AKA julia & nicks mom) and I thought I had it all figured out. I was traveling ahead of my family and I decided to buy the sweatshirts when I got to Florida instead of packing 6 sweatshirts in my suitcase on the plane. Transportation was crazy but we came from 4 different directions and finally assembled at Disney. Anyway I could not find white sweatshirts anywhere in the town where my parents live in FL. I had already printed the transfer sheets onto the light transfer paper. So with no white I opted for a grey. Well I tried one first on just a white teeshirt and I guess I scorched it because the backgroud turned yellow on my in several areas. I was so afraid it would not stick that I must have over ironed it! I moved to the grey and discovered that it left a block of darker grey where the blank part of the paper was. I guess I should have cut off the excess around the pattern? They still turned out cute but the color was not a vibrant as I would have liked and I noticed the dark part every time I saw them! We worn them a lot because it was so cold! Here is a photo of the kids wearing them. I want to make tee-shirts for our trip this spring so I guess I better figure out how to do it better!
