I couple years ago, I made a nativity out of felt. I decided to make some trees to go around it to add to the scene.
Here's what you need:
Styrofoam cones in various sizes
For the first tree, I used some brown yarn. I first hot glued a piece of felt to the bottom of the tree, cut to fit. Then I just started wrapping the yarn around, hot gluing every so often.
For the next tree, I covered it with felt. I made this simple pattern and cut out the shape from various colors of felt.
When I got to the top, I glued a circle around the top and then continued with the overlapping felt.
Last one! Using a larger circle punch, I punched many circles out of scrapbook paper.
Last thing I did was make a felt star, by tracing a cookie cutter onto felt.
