I got 2 sheets of 4x8 feet insulation at the hardware store and pinned flannel backed tablecloths to them with the flannel side out of course. They are just propped up against the wall behind a portable table. The tablecloths don't cover the insulation completely but I'm ok with that. The reason for the insulation is that it's very light. I would give credit to the person I copied this idea from if I knew who it was.
I'd like something fancier someday, like the hinged ones I saw here not too long ago but for now this is fine for me.
