What are you most proud of? I love that they are re-purposing favourite shirts that maybe no longer fit or that you just want to keep but not wear. They are cozy and functional.... and hey, if you spill on them, you take 'em off and throw them in the wash like you probably did 100 times before it became a pillow! What advice would you give someone starting this project? If you have printing on the back of the t-shirt that you want to show on the outside, make sure that when you pin the right sides together that the back 1/2 that you want showing is pinned closest to the right side of the front.... otherwise when you turn it right side out, the envelope won't work out with what you want showing. I am discovering that you can do with with any shaped pillow... just make sure to add 1 inch all the way around, and then add at least 4 inches to the back for the envelope overlap.
