| Start with a strip of fabric, your desired width, and one and a half to two times the length of what you're sewing it to |
| Adjust your machine to a strait stitch, in the longest stitch length available. Then loosen your top thread tension all the way |
| Sew two parallel lines down the side of your strip, leaving long threads at the ends |
| Then find the bottom (bobbin) threads.... |
| And pull them with one hand, while gently pushing your fabric away from them with the other hand. |
| Then pin your ruffle to whatever it is your sewing it to, with right sides facing each other. |
| When you sew your ruffle on, change your stitch length/tension back to normal, and be sure that you sew your new stitches above your gathering stitches, so they don't show when it's done. |
| Then you may pull out your gathering stitches, if you'd like! |
