Two-tailed project! One fabric, one silicone

[Dancing Fish]

Well, hell. A quick online search says (1) don't do it in the cold (ideal temps 60-70 F) and (2) if you do, use more hardener. I used less because the can said to do that if you mix big quantities.

I probably didn't need to pour it so thickly either. Meh. Eh, well. Worst comes to worst, I wasted a bunch of resin and a pretty dorsal mold, but I can do that again.
