I'm helping my nephew's wife make one of some of their memorable t-shirts. She wanted random sizes similar to the quilt pictured above. We laid the roughly cut pieces (cut with the rotary cutter, so they are squared up, just not sized) all out (after ironing lightweight interfacing on the back of them) and tried to come up with sets of pieces to form larger units to be sewn together. Several small pieces sewn together to equal the width of a larger a piece. Sew, then trim to to even up. I'm a fly-by-the-seat-of-my-pants person. So far we've got several units sewn together. We are saving pieces of the shirts with no pictures just in case we need some little strips for fillers. I hope I've got her going in the right direction. :-)
