I've wondered the same thing.... and when anyone makes a tote by a particular pattern, do they really add a tag or something saying such and such pattern by such and such designer? I know I have seen things at craft fairs that someone must have created from patterns but I don't ever see the pattern/designer noted..... and nobody (except the company/designer) seems to think anything about this. Do professional seamstresses attach a tag of "Simplicity Pattern ####' in their work?
