attached photos of the deformed drawer, I found out only after reassembling!
The cabinet itself, and 3 smaller drawers on the other side are all fine, but this one shocked me! Basically, it is made of plywood, with 3 false sides made of Oak, I chose the higher quality plywood that looks nice to touch and just required light sanding.
I took weeks as I was planning, cutting, assembling, waiting for nice sunny day for the painting (I used primer, then Rustoleum white gloss paint) - the process until painting took months, about 4 months from start! Maybe 3 months for the plywood of that particular drawer, so it's hard to believe it was humid inside..
I tried clamping the edge with a bar for 48 hours but it unfortunately did not keep the shape :( It seems to be the plywood that is deformed, not the actual fake full wood panels..
What do I do now? any advice? Its so beautiful, almost ready to mount!
