If you can get your hands on some of those dome tent poles that breakdown, you can make a collapsable set from them. Just use one or two pieces and shorten the shock cord that runs inside of it. Make sure you don't let the cord go when you are cutting it though, or you're never gonna get it back through there.
Then bind them together about 6" from the ends by winding some of the spare cord around and tying it off.
Hope this makes sense.
