I made a forest of these tiny felt tree pins last Christmas. They're simple, fast, and cute--my favorite kind of craft. And, at just about two inches tall, they're a great project for using up scraps of felt.
To make each tree, cut two triangles from the felt color of your choice. I made the pins shown here in a mod palette of bright pink and neon green, but I've also made them in traditional green and red. Decorate one triangle with buttons, beads, sequins, and simple embroidery. Be sure to leave a narrow border around the embellishments so you'll have enough room to stitch the tree pieces together.
Cut a triangle slightly smaller than the felt triangles from polyester batting. For the trunk, cut a small scrap in a color that contrasts with the tree. Stitch a pin backing onto the back piece of the tree before sewing the pieces together. Sandwich the batting triangle between the felt triangles and tuck the trunk between the felt pieces at the base of the tree. Use matching or coordinating embroidery floss and a running stitch to sew the front and back of the tree together, stitching through the trunk piece so it stays in place.
Be warned: these little trees are addictive. If you're like me, you'll want to try all kinds of color and embellishment combinations.
