a great way to "hide" moth holes, stains and other flaws on vintage cardigans & sweaters. create a cluster of fabric rosettes in matching/coordinating colors. for each rosette, cut a fabric circle that is about twice as large as you want the final rosette to be. fold over the edges slightly and do a running stitch all around the edge (make sure there is a thick knot at the beginning). gather the stitched thread (and fabric) together and flatten the rosette in place. use a few more stitches to make sure the rosette stays in place & to secure it to the sweater. done!
