Brilliant! I just found an old school room divider screen thingy at a rummage sale. It is ugly and needs a facelift but I set it up between my two toddlers today and it worked! I've been wanting some for a while but they are pricey. I never would have thought of the sheet setup and I like to sew so this is something I could probably make!
