In order to bend the 1/4"-think plywood, I grabbed a rag and a bucket of water and soaked both sides of the plywood. Then, turning the plywood good side up, I clamped it between two sticks and tightened the clamps. The wood will bend easily, without cracking. I let this dry overnight. The plywood springs back about halfway, but the wood fibers have been stretched sufficiently so it's easily bent and installed.
