A serving dish is meant to attract attention -- here we just moved it from table to door. Secure a strong, thick ribbon to hang (we used hot-glue), and tie on antique ornaments for color. Use a bit of removable puddy to attach the ornaments to the tray so they don't jostle when the door opens.
Let a favorite winter sport dominate your door decor. In place of wreath, cleaned-up ice skates make a lovely greeting. Secure them to the door in a few spots so they don't swing out when the door opens; then stuff with evergreens, ribbon, and leaves.
Circle up some bottom-of-the-tree cuttings for a nature-inspired wreath that's far from ordinary. Hot-glue together one layer, attaching the cuttings on the sides, then form a second layer on top by hot-gluing the cuttings when the first layer meets. Finish with an imaginative bow.
Raid the kitchen for wreath-spiration. Smell-good cinnamon circles up for a wreath that plays on seasonal tastes, smells, and good looks.
Ceiling tiles look just as pretty on doorways. Search antiques stores for a good-looking circle tile, then prime and paint a Chrsitmas color. Attach a contrasting bow to hang on your door.
