There are a number of stitches that can be used with appliqué to achieve different looks and uses. One of the most common is a blanket stitch, also known as an e-stitch.
The stitches work well on non-wovens and fabrics that don't fray. An e-stitch is charming and effective on children's clothing and creates an old-fashioned look on household goods. The edge is decorative and utilitarian, with a minimum of stitches.
