I made one out of PVC pipes and headliner cloth found the idea here on the QB

I have limited room. I had made one using styofoam, but it was a problem storing when not in use. Using the PVC pipe frame I can take it down and store the pipes in a wastebasket that will fit in the closet. The headliner I roll up and it fits in the closet also. Works great
