Ref: my July 16 post. Okay, I messed up pretty good. I got in a hurry last week to make some white mahogany (aka "primavera") plywood to back a china cabinet under construction. I did not go back and re-read the posts and follow the good suggestions offered up by this forum. No, I just slapped some white glue on my thin stock and backing board (cheap 1/4" ply), stuck them together without crossing the grain and weighted them down with gas cans, cement bags - anything lying around. Surprised me, but the end product looked pretty good. A week later, the boards were cupped and the thin stock had split. Ruined.
So, learn from my mistake.
This weekend, I'm going to follow the forum advice - use contact cement, a J roller, and cross the grain. Hopefully, I will have better results.
Stupid. There's no other word to describe my actions last week.
