- The red one - this is the one I chose. It is for a low shank. Most newer machines will use this.
- The blue one - this is mostly for older machines
- The yellow one - this is for high shanks. One side is for straight needles and the other is for slanted needles.
Next, take out the zipper and iron it so that the teeth are open.
The other very helpful thing I found out was to sew a basting stitch where you would like the seam to be. Do this for both sides. This really saved me. It provides a great guideline when sewing.
Place the front of the zipper on the front of the dress (right sides together, just like sewing other parts of the dress) so that the teeth are closest to the finished edge and the tape is near the seam.
Sew so that the needle is just beside the teeth. There are two tracks on the foot, so you will be able to position it, no matter which side you are sewing.
Now that one edge is finished, zip up the zipper and mark any seams or other points you need to match. For example, I marked the seam between the waist and the bodice on the zipper tape so that when I pin it to the other side, I know where to position it.
Pin second side in the same way. Although, technically, I didn't pin it. I should have. I swear. But I did use the seam marks as a guideline to put in the second side. I also had a basting stitch to follow as a guideline.
Finish the seam. The third useful thing was to not sew any of the seam until the zipper is in. Be careful not to sew any of the zipper, but get as close as possible.
Remove the basting stitches.
The zipper was flawless the first time I put it in without any hand-sewing. I had no idea it was this easy and quick.
Next steps: maybe read my sewing machine manual... I could have saved some frustration about zipper installation.
