Two recent projects:
The hand, done by a child with assistance from me, is based on this tutorial on YouTube; papier mache over wire, wood skewers, and rolled paper, with hot glue inside forming the knuckles and holding the structure together. It is unpainted in the picture.
The star was crocheted of dollar store string, five triangles crocheted onto a circle, then dipped into white paint, squeezed out, and dried flat. Much of the star was done while babywearing.
