Are you still holding on to too many old holiday cards and little tiny figurines, toys & knickknacks? Turn them into decorations!
Photograph the ones you want to remember, but don't need to keep, and just put the picture up on Flickr with the story that goes with it.
Then cut out the pretty part of the cards (as Katie describes here), add a little twisted wire loop around the small objects, and thread a bright ribbon to hang them on your mantelpiece, in your windows, on a Christmas tree or from your picture rails.
Put some in your car or purse or backpack to give as a little gift when you visit people or attach them to presents instead of a bow.
At the end of the holidays, box away any you still love to use next year, save the ones you aren't quite ready to toss in a give-to-friends bag, and go hang the rest from parking meters or mailboxes!
