when I read about the double knits I just remembered the first lap quilt I made if you can call it that. It was made with probably 4in.squares of plain orange and plain white double knit fabric, I sewed each square individually and stuffed them with fiberfill and then sewed them together by hand with blind stitch! It was well used but everytime I washed it I had to do repair stitches, it ended up in the dogs bed eventually. I still have to make a bed size quilt,sometime.
