Cedar tray hydration

[Footbag]

I'm with these guys, but instead of a sponge, I use a cotton rag that is very very slightly damp. If you are saturating the wood, you're going too far.

I don't think storing the trays in 98% humidity 90 degrees (bathroom)would be the best idea. Not that you'll really experience any problems, but it could potentially swell the joints. Better to do it slowly.
