Nothing major, but I put a few sticker designs up on StickerMule's marketplace: https://www.stickermule.com/user/1070831731/stickers

It's been a couple months, and my $20ish investment (you have to place an order for a sticker before you can sell it) has turned up $43 of profit. So technically it was profitable, but I don't think I've even reached minimum wage for the time I spent on it.
