I learned to sew in Girl Scouts years ago. I can’t even tell you how many ruffles I’ve made in my lifetime. Here’s is a super easy technique. I wish I’d known about this years ago.
Start with a strip of your favorite fabric.
Set your machine to the longest stitch length.
Set your tension to the highest number.
Start sewing slowly. You’ll notice the ruffle forming behind your presser foot.
Make sure you leave long thread ends at both the beginning and end, and don’t backstitch. You can adjust these threads to get your ruffle to be just as ruffly as you prefer.
Voila! Automatic ruffles!
I love adding ruffles to things. My kids and dog better keep moving!
