I hung a traverse rod up in our quilting room (bought at Sears). You can spread the rod to almost any legnth you want. Buy some curtain hooks and hang a sheet and there you go. When you need it, spread it out and pin up your quilt pieces and when you're done, collapse it just like a curtain. Here is the link of my DW's post.
