I think kids need to make things as part of their ongoing development.
I personally like things that have some function. I went to Michaels (the land of pipe cleaners and googly eyes) and got a few things. I wanted to introduce glue. I didn’t really have a good project in mind so in a last minute scramble I made some boxes out of carboard and hardboard (that would need gluing) and two cardboard elephants. In my mind I was still trying to think of something that had more use (or at least moving parts).
We glued and painted and I kept thinking.
In the end, the stuff we were making does have a good use. My mind simply wasn’t open enough (see below).
