I have tons of them too! I have machine stitched them together using zigzag stitch and just tacking at top, bottom, left, and right sides. Like this, I use them as table toppers, have a long one on my TV stand, works well to disguise the dust! LOL! Also used as decorative on a tote bag, in fact, just last night, I had finished a tote bag, didn't have the snap on, should have been done before finishing the bag, but I just put it anyway, then hand sewed a yo-yo on each side to cover the snap! Not gonna post pic because quilt police would chew me up and spit me out! You can press them down, then machine stitch onto a background fabric like some of the quilts shown on some of the above links, I have a whole bag of red/pink, different shades, want to make one all red and white background.......someday!
