I made two badges for myself today. Well, actually six, but I kept two of them.
1 - Crudely coloured strawberry. I made it to make sure the badge machine still worked. Rejected.
2 - A piece of styrofoam. It was in the box I opened, using the scissors I accidentally cut my arm with. I wanted to see what would happen. It was boring. Rejected.
3 - Doctor Whoof! I attempted to draw the MLP DW-like character. I failed. Rejected.
4 - A Ravenclaw badge. The grey I used was way too dark to look like silver. Rejected.
5 - A TARDIS badge. Simple, and not that good. But I liked it. Kept!
6 - A Weeping Angel badge. I think it turned out well, given how I'm really bad at drawing. Kept!
