Best wishes! We had one of similar design but smaller. We nicknamed it the DevilTent because it enticed us into the ease that it went up, lightness etc, but when it came time to leave we could never get the thing to fold in to the circle. Finally gave it to a nephew (physics degree) who had mastered the secret. By the way he got it in it's wonderful open state. Hopefully you too will be an origami master (We own a clam and love it)
