I was at the Quilt Expo in Madison, WI and there was a person in a booth demonstrating the 606 spray adhesive. She used it on the back of the sections of the tshirts she wanted to use in the quilt, cut them out and then ironed the pieces on a large piece of black fabric....no sewing and the effect was so cool! I bought 3 cans of the stuff for not only tshirt quilts but banners and applique! The 606 spray is permanent, the edges of the pieces do not ravel.
