The Blanket Stitch is simple, easy and beautiful. It is called Blanket Stitch, as traditionally, it is used to stitch the edges of blankets. It gives the blanket edges a nice look and secures them. This stitch is now used in many other crafting projects, making it one of the most sought-after stitches.
The Blanket Stitch is often confused with the Buttonhole Stitch. Instead, it should be said that Blanket Stitch and Buttonhole Stitch are often considered the same. While some extensive research would logically explain that they are not. While both stitches are used to secure edges, a Buttonhole Stitch is a sturdier one. So, traditionally, tailors would hand sew the Buttonhole Stitch to the edges of buttonholes.
