Okie, if you have a Tumblr you should already know what Fanpro is or at least be aware of it's existence. If you don't know what it is let me explain it to you because it's really interesting. First of all, it's short for Fandom Project, and it's exactly what it's name implies, and project of a fandom. But what fandom? A new one, the goal was to start a new fandom as a social movement for this girl but that turned out to be false. But guess what? That didn't stop us, the project is still going strong and it's only been out for about a week.
There's supposed to be 1000 designs in total, the first 100 were created by the fandom starters, the designs are really crude
but that's so you can interpret them as you want. That's right, interpret them as you want, this even includes giving them headcannons, so they can literally be whatever you want.
Right now there are 120 Fanpro designs, they just accepted 0101-0120 today and are going to be accepting designs every Friday, 20 each Friday to be exact. You (or anyone) can submit the designs, I submitted two and one of them made it in and she already has fanart. Oh yeah, and the designs are also Royalty Free, so you can make merchandise of any of designs without having to credit any of the original creators and stuff and can make big bank if it gets big enough and your stuff sells.
If you have anymore more questions you can visit their official Tumblr
but I recommend reading through their post and F.A.Q. first before asking anything.
