L.M.
I'M being dense is it that you 4 adults will exchange? or that the families will exchange? or that each child will get a gift?
I would hate to have to buy and store and manage even MORE stuff. so i would think, either each family brings a board game and you raffle it off some how
or do a cookie exchange,or something else edible
I hesitate to even do like one dollar stocking stuffer stuff.
could you exchange used movies or books?
