1. Cut out triangles for the tree. I cut out 3 green triangles for the front, and 3 orange triangles for the back. I just eyeballed the green set, and then made the orange set match in size. I also cut out two little brown scraps for the tree trunk.
3. With the wrong sides together, zig zag around each triangle and the tree trunk. I also inserted the ends of a bit of ribbon I had lying around into the top point of the tree.
