After dinner though, I sat down with a pair of scissors and started cutting apart shirts. It is so fun to see all the shirts and the events that they each represent. Schools, scouts, vacations, sports... what a fun collection.
After rough cutting the fronts, I dug out the lightweight fusible interfacing and cut out some 13 inch squares. When I've done adult quilts, the shirts ended up somewhere around 18 inches square, but these are kid sized shirts, so 12 inches is going to work better in this case. The interfacing gets ironed onto the back, centered behind the design.
