We have drafty old windows in our house. It seemed like a curtain barrier of some sort would be a good idea, but the curtains you find at Wally world seem to just be too thin. So I bought some very thick fabric, had my husband install a curtain rod, and safety-pinned my way into a fairly decent set of draft diverting drapes. Much like Daniel's thermabond hemmed curtains, these have nary a stitch holding them together. If nothing else, I am feeling efficient and resourceful today! :0)
