Congrats on the v1 launch! Signed up last night, I'll be giving it a thorough investigate today.
One thing I did immediately notice though is that some of your supported patterns aren't actually available, the first one I clicked on was "Wreath of Leaves" and it leads to a dead end on Etsy. That could potentially be a really big issue if you're hoping to grow the pattern catalogue and get other designers on board, trying to maintain active links for everything would be a moderation nightmare. Just something to think about if you haven't already.
