Punch holes in the leaves and string with a one to two foot length of fishing line, securing with a knot.
Invite your child to string on as many, or as few, beads as she or he would like. When the lengths are finished, they can tie them onto the mason lid. About four or five beaded leaf strings creates a nicely balanced mobile. Finish things off with a one to two foot piece of ribbon or twine for hanging in an entry way or corner of a room near a window.
