- First, baste your pieces with a regular zigzag stitch (medium width, approximately 10 stitches per inch). VERY IMPORTANT: "ZIG" on the fabric and "ZAG" in the air as you can see in the video.
- Sew a straight stitch (again, regular length - not too long or too short). As you can see, she bar tacks at the beginning and then STRETCH THE FABRIC GENTLY as she goes. This way, the fabric keeps pretty much it's original stretch.
- This step is optional, but will reinforce your seam. It's another straight stitch, right over the first one. You have to stretch the fabric again, just like you did the first time:
It's as simple as that! Here you can see that our "regular machine stitch" has as enough stretch as the serger stitch. Before you make your first swimsuit for yourself or a skating dress for a loved one, take some fabric and practice the technique so you know how much you have to pull to have a nice stretchy seam :)
