DYI Stand - which plywood?

[Myka]

It's depends how beefy your framing is. I'm happy using 1/8" for the back and 1/4" for the sides. If you're using European hinges they require the mounting surface and the doors to be 3/4" plywood for easiest installation (many others require this too) since typical kitchen cabinets are 3/4". If you're using magnets to hold the panels instead of fabricating doors, then sometimes 1/8" works better because the magnets are stronger than the wood's ability to warp, but 3/4" is much more durable. I've always just used standard sanded plywood.
