Make a bow tie out of the fabric. You can sew or glue the ends of the bow tie together.
Use the buttons as a template and cut out three circles from the felt a yellow, orange and a green circle slightly larger than the buttons. Sew the buttons with the light green thread at the top of the sock.
Wrap the wool threads around your index finger and small finger, wrap a wool thread around the middle and tighten. Gently knot the threads and cut the loop ends.
Sew the finished pom-pom over the largest button. The pom-pom imitates hair.
Cut out the mouth from dark green felt and sew it on the sock. Glue colorful feathers between the buttons. The first monster sock is ready!
