What stitch did you use to connect your biscuits? If you used a whip stitch, does the stitching show on one side? I'm wondering what stitch to use so that it can be reversible.
This really appeals to me. I like your ideas of using up scraps or old clothing and making just a few pieces at a time. I figure if I make a few each time I watch television, I should have enough in a year to make a quilt to cover up!
