OK - I admit it! I haven't got mine folded right from the first time I opened it. Instructions - I've read them over and over again and I've tried. Stuff it in the bag and weigh it down seems to work!
I'd better look for someone to teach me at the next camp!
I have a similar thing (sprung steel) that opens out into a drying support for clothes - I can get the right twist into that to pack it away!
