I recently made 3 for a coworker who lost her husband and she gave me t-shirts and cotton/silk hawaiian shirts. One great tip-stabilize all fabrics and t-shirts with fusible interfacing. I did not know that woven silk would stretch, but I found out the hard way. Stabilize the t-shirst before cutting to keep the fabric from curling. They were crazy quilts with picture transfers. If it had of been only t-shirts, I could have squared up better and made more uniform. Hope this helps! To see pics, go to Pictures, My labor of love on January 6, 2011.
