I've built many raised panels for cabinets and etc. now I have a need to put flat panels in my rail and stile door frames. I normally use 4/4 ruff cut milling it down to 3/4 oak and I'm really puzzled on how to do the panels without just planning the panels down from 3/4 stock. I would hate to waste good 3/4 stock making flat panels. I try not to use ply but might consider it if need be. Resawing? maybe but I could see having problems glueing and getting them flat.
How and what do you folks use for your flat panels?
