I just made an I spy quilt. Just have to bind it. I’m keeping a pack of fabrics for I spy. I do the boom swaps and many time I do have a little bit of fabric leftover that I can use for I spy quilts. And a few years ago we had an I spy swap, I sent in 20 or 40 squares ( several different fabrics) and got back 40 different squares. The swap was on the quilting board.
