Materials:
crossed boughs
wide ribbon, wired or unwired (or buy pre-made bows - 1 large and a couple small)
wire
wire cutters
hot glue
ornaments

Directions:
If you can't buy crossed boughs, you can buy individual ones and wire them together. You can also make this with real fir boughs.
Use some wire to make a hanging hook where the boughs cross over on the back.
Attach the big bow at the top, and a couple of small ones down along each side (you can use the small ornaments in place of the small bows).
