To answer your question, if you buy new you should get consistent sizing, with the exception of the frog print. Those seem to be running large.
However just be aware that FB's, as well as most other diapers, are protected by a patent, and it's illegal to copy them. Especially if you are planning to sell them. So if you do copy them I wouldn't be spreading it around too much.
