Hi, please accept my prayers for your loss. I've taught a couple of t-shirt quilt classes. I use Pellon 911 fusible. One tip I always teach is buy a teflon pressing sheet. JoAnn's has them and they are available on line. Put the sheet on your ironing board the t-shirt goes on top face down, then the fusible then the damp pressing sheet. The teflon serves 2 uses: 1. it protects your ironing board from the interfacing gunk and 2. it will keep the design on the t-shirt from transferring onto your ironing surface. Last, when you go to quilt, don't quilt across the design if it is plastic or feel like thick paint, if you break its bond with the fabric while quilting it can peel off.
