Wear a green sweat suit. Cut leaf shapes out of green felt and glue them here and there on your sweat suit. Using the same color felt cut out two 2 - 3 inch strip that is long enough to fit around your neck and over lay on the back by about an inch. Cut large petal shapes out of felt (whatever color you want). Glue the straight edge of the petals along the edge of one of your felt strips. Glue the other felt strip on top of the petal edges and the other felt strip to secure them in place. Once the glue is dry, use self-adhesive velcro on the strip to make a "collar" out of the strip you cut.
