You want "Benderboard". Any pro plywood source will carry benderboard
of some type. It is thin springy plywood, made to be bent about a
frame. You can roll that suuff up into a 12" tube easy. It usually
comes with the bendability in one dimension or the other, so be sure
to the kind that bends along the long length.
