I used heavy white card stock for the trees, and created trunks using cinnamon stick segments. Then I glued on twine loops, which I attached to a longer string-- and done!
I picked up a ton of unfinished wood decorations at the craft store (none over $5-- a great deal). I painted some of these wooden trees with a light coat of white opalescent paint-- it comes off as a stain in the most wonderful way-- and I painted the stands flat brown. I stuck one in a jar I had painted and wrapped with twine, and let the others alone, adding a few pine cones.
For our mobiles (which I highly recommend picking up-- they are so versatile and super easy to change out every season) I used more wood pieces (only 29 cents each, if you can believe it). I spray painted the snowflakes flat white, and used brown for the moose and deer.
Tomorrow I'll post a house tour, so you can see all the goodies I've made in place. We are all so excited this year-- can you believe Christmas is only 4 days away??
