Very cool! Should probably mention that the stars are glued on? After all, origami is only folding, no glue.
Thanks What I know is that in kusudama you can use glue. You can see it in most of the kusudama projects.
All kusadama are made to be put together without glue. Glue is just a reinforcement!
Some of them are, but not all. You should check out for example "morning dew kusudama", which is entirely glued, and without it the parts wouldn't come together at all.
