Man that demo sounds legit, 500 flips is no joke. I had a similar moment when I grabbed a bottle of Lineco PVA on a whim at a local shop. Used it on a paperback repair and that thing's still holding strong after two years. Wheat paste is fine and all but the PVA just feels more solid for hinges. Glad you found something that works, it's a game changer when you see it in person.

Respectfully, I think fancy degrees actually save you from a lot of expensive mistakes.

Used to think that was a scam, but it actually works.

Seems like a lot of fuss over a notebook that probably cost fifteen bucks.

Those lenticular clouds over Hood are something else - did you notice if they stayed dead still or drifted slowly before breaking apart?
