Trace the stocking pattern onto tracing paper; cut out.
Use the pattern to cut one stocking front from sweater. If using part of a sweater with buttons, use sewing thread and needle to tack opening closed. For a cuff, add 3 to 4 inches of sweater at top of the pattern. From felt, cut out a lining and a back. Cut one stocking shape from fusible webbing.
Following manufacturer's instructions, fuse stocking front to one felt lining piece using fusible webbing.
Sew decorative trims, such as buttons, pom-poms, or fringe, to stocking front. To add fringe, use a crochet hook to pull yarn loops through cuff edge.
Sew stocking front to back around the edges, using a 1/4-inch seam, leaving an opening at the top.
Turn your stash of ugly sweaters into adorable Christmas stockings with this clever project.
