Seeing as you didn't address the poster above's point about copyright I thought I'd post some of the copyright notices that apply to patterns you used. Hopefully this will be useful to anyone else considering knitting items on commission too. Magknits legal info
"All patterns on this site are provided free for personal use. Items made from these patterns may not be sold for profit."Knitty's legal info
"You may print out a copy to work with. But you may not print out multiple copies, you may not reformat the pattern for commercial use, and you may not sell them or items made FROM Knitty patterns. The copyright for each pattern and article belongs to the designer or author. Any usage beyond what's mentioned here must be negotiated with the designer or author."
Copyright info for Ohmystars,
source of the razor cami pattern:
"all patterns remain property of ohmystars. do not copy, redistrubute, or sell for profit - that includes finished pieces too. you may of course print for your own non-commercial reference use."
As you can see these all expressly forbid selling items made from these patterns without the permission of the designer. Most knitty and magknits patterns include the designer's email so it may be worth asking for permission. Of course I don't know that you haven't already done that, but I'm basing my assumption on the fact that you haven't credited any of the designers.
