Blue satin stitches are around the edges of the flames to the right.
The satin stitch is a decorative stitch that often is used to border appliqued pieces. The stitch is actually a zig zag stitch with zero stitch length. Some sort of stabilizer is usually needed when making this stitch as it has a tendency to “pull up” the fabric around the stitching. It’s a good idea to experiment with scraps of fabric before committing to your project’s fabric.
