Totally agree on the paint trends. I jumped on the milk paint bandwagon last year for a coffee table project (thinking I'd be all rustic and chic). Followed the mix instructions to the letter, but it dried all patchy and weird, like a cow sneezed on it. Had to sand the whole thing down and start over with regular paint, which was honestly a relief.

Wait, animal glue can actually get brittle? I always thought it stayed flexible forever.
