Colorful and beautifully crafted, hand-stitched felt wings can turn anyone into a bright butterfly. Combine them with a plain black top and pants, and a headband with pipe-cleaner antennae.
Tools and Materials
1 1/2 yards dark brown wool felt
Butterfly Template http://images.marthastewart.com/images/content/web/pdfs/2010Q4/sip_hall10_mademoisellebutterfly.pdf
1 yard polyurethane foam
1/4 yard blue felt
8 by 10 inches each of orange, white, and green felt
Needle and thread
1-inch-wide black elastic
2 brown pipe cleaners
Mademoiselle Butterfly How-To
Fold dark brown felt in half; place template on top, aligning left side with fold, and cut out (do not cut at fold). Repeat with piece of foam. Repeat process with remaining brown felt and foam, this time cutting along the fold. Cut out 2 sets of markings from colored felt, using template as a guide. Topstitch markings to each felt wing. Stack pieces as follows: whole foam wing; whole felt wing, faceup; felt half wings, facedown; foam half wings. Stitch around perimeter with a 1/4-inch seam allowance. Turn right side out. Whipstitch center opening closed; this will be underside of wings.
Cut elastic into two 11-inch strips; hand-sew crossed straps onto underside of wings as shown, stitching through one layer of felt and foam. To make antennae, wrap pipe cleaners around headband; curl ends.
