This stitch is simple and easy, yet a beauty. It is called balnket stitch as traditionally, it is used to stitch the edges of blankets. It not only gives the blanket edges a nice look, but also secures it. This stitch is now used used in many other crafting projects as well. This is one of the most sought after stitches.

Blanket stitch is often confused with the buttonhole stitch. Or, rather, it should be said that blanket stitch and buttonhole stitch are oftern considered to be the same. While, some extensive research would logically explain that they are not.

While both stitches are used to secure edges, buttonhole stitch is a sturdier stitch to secure edges of buttonholes. So, traditionally, tailors would use the buttonhole stitch to hand sew the edges of buttonholes.

Blanket stitch can be sewn from left to right or right to left. I prefer the left to right direction. I have illustrated this stitch between two horizontally parallel stitch lines.
