I know, more or less, where to buy legit anime/manga goods, figurines, etc. I also know how to find Japanese doujinshi!

What I'm looking for, though, is how to find fan-made goods outside of convention alleys.
Bookmarks, small posters, etc. with fanart, maybe some buttons or jewelry. Is there an Internet place to do this? I try searching Etsy sometimes, but I figure there must be more? Pickings there seem slim.
