Last month at the preschool we made glass bead icicles. Each child selected their beads and got a piece of fish line with a knot in the end to string them on. I also gave each child a square of wool to set their beads on so they would not roll all over the place. Once they were satisified with how their icicle looked, I tied the top with a loop for hanging.
This was a great exercise in using those fine motor skills.
