1. Pin a stocking shape cut from bright red felt on top of a larger piece of dark red felt. Sew together by machine-stitching side and bottom edges.
2. Trim dark red felt, leaving a 1/4-inch border along stitch line. With a running stitch and white embroidery floss, go over the machine stitching for hand-sewn detailing.
3. To create the largest flower, layer white-felt petal shapes on top of aqua felt and secure with aqua embroidery floss. Cut out a 2 1/4-inch dark blue felt circle and a 1 3/4-inch red felt circle. Notch the circle edges. Layer a white-felt circle on top of the notched circles and sew the petals to the three-layer flower center. Sew a doubled-up button through the flower center. Sew flower to stocking.
4. Make smaller two-ply flower shapes. Layer felt shapes and buttons and stitch to stocking. Sew small shank buttons directly to stocking for additional detail.
