So I have this bright orange cardigan that I bought a few years ago (mainly because it was on sale). It fits great, but sometimes when I wear it I feel like I should be at a San Francisco Giants game. And, let's just say I'm not a huge Giants fan. So I decided to make it prettier. Adding a ruffle in a lighter color can help soften an overly bright item of clothing.
Find a cardigan that fits well, but that you are not in love with.
Find some fabric with a color that complements the color of your sweater and cut a long (45-inch) strip about one-inch wide. I used some ivory-colored fabric that I found on clearance ($2.95/yard!)
Then sew a ruffle stitch down the center of the strip by setting your sewing machine to the highest tension and longest stitch length. (It should be set to a straight stitch and not a zigzag stitch like it is here. Oops)
You will end up with a ruffle about half the length of what you started with. (So in this case, about 22 inches long)
Then pin the ruffle in a curvy pattern starting about 1/3 of the way from the bottom of the sweater and ending on the shoulder. There is nothing special about the design I picked, I just adjusted the ruffle until I liked the way it looked:
Set your sewing machine to a small straight stitch, and sew the ruffle to the sweater, using matching thread.
(Sorry for the poor picture quality on this last one. Getting a good self-portrait is harder than it looks. Dang.)
