It really bothers me to pay for 2 1/2 inch strips in a pre cut and then find out that they don't measure up. There is no reason these companies can't cut them correctly. I just used some Kafee Fasset jelly rolls. They were not the correct size. They were cut with a pinking sheers and even if I measured to the tips of the zig zag they were about 1/4 inch short. Luckily the pattern I did, as long as I was off the same amount all the time it worked out. I had the center of the quilt finished before I realized they were off. I didn't know they were cut wrong until I tried to make a border out of the leftover strips and put them with some 2 1/2 strips I cut myself. These companies should be ashamed of themselves.
