This fun Christmas tree is made with nothing but garden twine and regular white glue. Cover a styrofoam cone with plastic wrap to create a mold for your tree. Dip lengths of twine into white glue and wrap them around the cone, making sure the twine overlaps to strengthen the final tree. Let the glue dry completely, and gently pull out the mold. Decorate your finished tree with bright red berries for a festive touch.
