Sorry the OP didn't reply... but I "think" that he/she was going to try making the Jelly Roll Rug that is out there right now. It calls for approx. 40 @ 2 ½ " strips.... and if you fold them WS together... and place a 1 1/8" strip of batting into them..... the pattern (which I don't have) probably tells you how to stitch them and then roll them into a big ball and then start stitching them together..... I have been searching this out recently and found a few posts.... I am not interested in making a rug myself... but it would be fun to actually find out how close I am in my guesses.
