It was super tough to figure out how to make it stay up. We had to try at least four different ways to keep the "sails" up.
To make the "sails", we cut up a small paper cup into three parts and taped them onto about two centimeter beads with large holes in the middle.
To make the base we stuck three small scewers in to the bottom of a paper cut in different places.
The hardest thing was to was keep the the "sails" up so the LAST thing we tried was to get metal washers and put poster putty around the scewers. We put the washers onto the poster putty so the washers stuck then put the "sails" on.
It didn't work too well for us, but you can do whatever you want to make it work! Good luck!
