Oh I am so glad you posted this. I just started a DP9 and have charm packs from 3 different companies plus my own cutting. NONE of them are the same size! I decided to go ahead and sew them together and square up later. How frustrating! I have heard all or almost all pre cuts are the same way. Do they not have a real person that can read a ruler? I doubt I will be buying pre cuts again. I have better luck cutting my own from fat qtrs. and doing away with the little waste created.
