Are you going to use interfacing on the back of the shirt squares? Price out how much that alone will cost ( it’s expensive) If you decide to just do squares of the shirts and stabilize the sides from stretching too much with straight of grain fabric, it will be cheaper but trickier to sew. Also be aware that stitching over large plastic graphics from the shirts can be a difficult if not impossible endeavour. Work up a sheet of all your expenses, labour costs etc. and get half the money up front Before you begin. Chances are once she sees the cost, she will decline. Good Luck!
