I remember those nylon-stuffed biscuit quilts! They were popular for awhile. As I recall, it was touted as a wonderful way to recycle nylons. I didn't make one, but I know a lot of them were made with larger squares using corduroy for the squares. The technique, I think, was the one described above where you sew the biscuits with the seams enclosed (like little pillows) and then hand stitch together. I remember one like this featured on the cover of a magazine as a "modern" quilt! How time flies......
