    If you already own that plywood and it's not flat - you're probably out of luck. I once had some like that. Bought from the Borg. I did get it flat. But not in a way that's probably going to be of use to you. I used it for shelving. But I made a frame for underneath it then I glued and screwed it to that frame. Great! Now it's flat. But I know it doesn't want to be.

    Nowadays when I want flat(ish) plywood laid up of veneer, I go to a traditional lumberyard for it. It may not be absolutely flat (but what is?) but it *is* a lot better than what the Borg sells.

    MDF is pretty flat. Maybe you could use that.

    I've heard that if you lay it convex side down on the lawn for a day, it will pick up enough moisture on one side to flatten. If it's the same as the junk I see at my local big box, you may need to run the sprinklers for a few days too....
