I had an extra 4x8 tent with no frame so I built a frame out of 2x4's and 1x2's . The cool thing about building a frame with wood is it's much more sturdy, you can attach stuff to the frame easier (panda plastic can easily be used to partition off a section), and it only cost around $30 to build. Tip... if you do build a frame to fit a tent, make sure you build it 1" smaller than the dimensions of the tent. so a frame for a 4x8 tent would measure 47"x 95", This way the tent fits easily over the frame.
