The motif of a Christmas tree evokes the scent, joy and fun of the holiday season. Even if you can't have a real tree, you can still get a kick out of the shape of one.
There are lots of crafts to make with this motif; cookies in the shape of a tree, decorated with colored icing for tinsel and tiny silver balls for baubles, trees painted on windows to look like stained glass, a fake tree trimmed (literally) to look more primitive.
Decorate it with tiny birds nest (also faux) and you have a bird themed Christmas.
You can make full sized mock ups of Christmas trees out of barnboard.
Or make jeweled replicas of trees in a picture frame.
Or...the options are endless. If your favorite Christmas motif is a Christmas tree, have a look at my Pinterest board;
