Well hello there! If you've made it to this page, then you're probably interested in knitting my patterns and selling your pieces commercially. And if that's the case, then please, read on! Hopefully all of your questions will be answered (if not, you can always email me at email@example.com).
First and foremost, the obvious: please don't try to sell my patterns. I don't even do that, yo!
Secondly, and less obvious: if you're simply interested in selling finished pieces knit from my patterns, knock yourself out! Go to town! Have fun! Or, stated more clearly: you may knit my patterns and sell my pieces commercially, with my blessing. I would, however, prefer attribution for the pattern design. "Designed by Gretchen Tracy at Balls to the Walls Knits" or "Pattern can be found at www.ballstothewallsknits.com" or some version thereof works splendidly!
Thirdly, and even less obvious: if you're an Etsy seller and you've decided to produce my goods AND you're interested in advertising that fact right here on my website, shoot me an email. I would be happy to provide a link to your shop from the relevant pattern for a small advertising fee (I may even create a "Where to Buy" page if I get enough interest).
And finally: this information pertains to home-based sellers. If you're here sourcing knitwear design for the Gap, I'd rather you give me a job than poach my patterns!
