Yeah, @the_kim, vellum is actually made to not do that. It's a special drafting paper that's supposed to be stable. It doesn't soak up moisture from the air or your hand like regular paper, so it shouldn't warp or get wavy when you're drawing on it. Your friend's teacher probably used it so their ink lines wouldn't bleed or the paper wouldn't buckle. If it's doing "the same thing," they might have gotten a bad batch or it's not real vellum.

Wait, so if short nails can be wrong on some horses too, when do you actually pick length? I mean some farriers are flat out wrong sticking to long nails, right? What makes you choose one way over the other on a given day?

Reminds me @michael_wright90, I even killed a cactus once.

Yeah, the "constant stress" part isn't quite how it works. It's not a steady push, it's more like random big gusts and then long calm periods. The tree gets stronger because the heavy stress comes and goes, letting it adapt to the worst cases. A workshop is too even, you know? It misses those surprise hits.

Seriously, is a late fee worth the awkward conversation? Chasing clients for extra pennies can sour a good relationship faster than the late payment itself. I'd rather just drop slow payers and find better ones.
