Had the same problem with charms. Ended up recutting almost half of a package with my GoBaby so they would all be the same size. But I love precuts because I cannot cut straight - even with a ruler - and to cut yardage on a GoBaby wastes so much fabric AND you get such great variety with those charm packs. Now jelly rolls ARE a pain when they are not cut uniformly - and I have bought them from places where I felt that would not be a problem - but it was!
