I've been making hammocks and beds for my rats (might make a few cat beds too), because they don't care if it's not quite straight, messy here and there, etc. :D I'm just winging it usually, but I'm working on a tube-hammock thing now out of a trouser leg that I planned out, and it's looking really nice now. too bad it probably won't last long..let's just say once they're comfy in one place, they won't get up for anything. >_>
I'm gonna be really scared once I actually do my first shirt resize or something, haha.
