I have been a big fan of the sims from day one. I just recently with the release of the sims 3 have become a creator.
I don't mind if anyone use's my patterns for their own personally use that's what i upload them to the exchange for but do not claim them as your own or anything else i make as your own or i will stop sharing my creations.
I also appreciate it when I get recognition for the patterns I make. If your going to create clothing and a majority of that is with my patterns it only seems fair to give me credit for it on the download or your page.
