  • Keep in mind the fit of the garment. Do you want it to be tight or loose?
  • The hem determines the fit of each garment. Think about how much stretch you want.

Twin needle: for tight knits

Using a twin needle for your hem is the best stitch to use when sewing a cover stitch. This needle maximizes steaming capacity and results in a closer fitting garment.

Narrow zigzag: for looser fits

If if you plan to sew a narrower hem, the narrow zigzag stitch is the stitch for you. The narrow zigzag gives your garment more room for a looser fit.

This stitch can create a stretch hem that is useful for chunky knits. However, it is not so good for soft fabrics. Be sensible in choosing this stitch when you need it.
