1. Start out by buying a plain onesie, and some cute fabric. I chose jersey knit because it's super comfy for those newborns. This tutorial is for 18 month onesies, so measure accordingly.Cut your jersey strips 5-5.5 inches by 4 times the width of your onesie. You want to make sure that once you ruffle the fabric, it will be long enough to wrap all the way around.
2.Ruffle your strips of jersey by setting your machine on the highest length of stitch possible. Mine is a 6. I also adjusted the tension and my jersey ruffled up nicely by itself.
3. Once your strips are ruffled, check to make sure they are the right length. Then, sew it, right sides together. Now you should have a ruffled tube of fabric.
4. Pin your ruffles down onto the onesie where you want them placed. *Tip: I like the ruffles to dip a little lower in the back to accomadate for the diapers...And cute little buns :)
5.Sew your ruffles on with a zig-zag stitch, and pair it with a matching bow and Taggie Blanket and you have the perfect little shower gift!
