Tiny Origami Baskets? Yep.

These are shown for Easter but could just as easily be designed for anything - fairy garden, little legos, trinket holder, tiny stone collection... 
They are also shown as being created from an existing beautiful piece of paper, but I would encourage students to make a plain paper beautiful first - sponge paint, paint splatter, etc, and then fold when it's dry.
