Here's an EASY craft idea for your children: make a dream catcher!  We cut the middle out of a paper plate and my daughter colored the edges.  She chose various ribbons from my gift wrapping supplies and glued them to the back of the plate.  The feathers are from a boa we had in the playroom (if you have one, you could probably just pick some feathers up off the floor!).  Voila!  Easy dream catcher.  Would be a fun activity for a playdate :)
