Leaving the bag flat, cut thin strips from the top of the bag down about halfway or a little past. Each bag should have about 12-14 strips.
Open the bag then twist it where the bottom of the cut strips meets the uncut part of the bag so that you will make a trunk.
Now take 2-3 strips at a time and twist together tightly, these will be the branches of the tree.
Then tear little pieces of the colored paper for the leaves.
Glue a few leaves on each tree and sprinkle the rest at the base of the trees to resemble the leaves have fallen off the tree.
