Etiquette on selling
I'm new to quilting, and have been giving my 'practice runs' to family and friends so far. However, I think I'd like to try selling a few on Etsy or somewhere similar in the future. My question is really this: I've purchased patterns and books of patterns, but am not aware of if there's any legal restrictions on selling the quilts that I've made from those patterns? I'm not creative, so by and large I'm following the patterns down to the colors.
If it's not illegal in some way, is it considered bad form? I just don't want to step on toes if so.
Thanks in advance for helping a newbie out.
