Here are links to just a few of my favorite Christmas tree crafts:
Paper Christmas Tree - to create an adorable table top decoration
Pine Cone Christmas Tree - kids can spend hours finding pine cones in the yard to create these adorable ornaments (or you can buy pine cones at a craft store)
Little Christmas Tree Decoration - watch this video to learn how to make these cute little trees

Create this beautiful jewel-covered Christmas tree craft by drawing a Christmas tree on a piece of heavy white (or green) card stock.  Cut out the trees. Then glue green jewels around the edge of the tree to create a green tree outline.  If you can find brown jewels, you can use those to outline the trunk.  Use red jewels to create a zig-zag garland pattern and tree topper. Then, glue on any color of jewels that you like to make "ornaments" on the tree.  These beautiful jeweled creations can be glued on Christmas gift basketsto give them some pizazz or we often use them as gift hang tags by punching a small hole in them and tying on a small ribbon to attach them to the wrapped gift bag or Christmas gift box.
