I would recommend you hold on to that extra fabric until you have all the blocks finished. I don't do kits very often--tend to buy them and set aside and then work on a year or two later. Anyway, did two last year and had plenty left, working on one from Connecting Threads and while their 2 jelly rolls were more than enough, the yardage just did not come close to being enough. Luckily it's a blender!
