That is this forum. It's mainly for members to buy, sell or swap yarn and accessories like like needles, books etc. We don't want people setting up shop in here to sell patterns though. KH just isn't set up for large scale pattern sales like Ravelry or Etsy.
I see now that you do sell patterns on Ravelry. Other than your own website that really is the best place to try and sell them.
One more thing...if you do create your own website for your patterns you can contact Sheldon about purchasing an ad here in KH for your website. I'm not sure what criteria he uses, but that's how you'd go about it.
