A. has been fashioning hats for himself and his friends, using various cutting-edge materials.
The above hats were made out of kleenex. He put the kleenex wad on the giraffe’s head, saying “Hat.” These hats were of the variety that can be worn two or three at a time.

He is adorable.
C made himself a hat yesterday. Out of a pancake.
I have a book recommendation for you: “Caps for Sale” by Esphyr Slobodkina. It has lots of hats AND monkeys. It’s a classic!
