Moss is a crochet stitch, universal, popular, and nice too.

The Arrow is a characteristic method of shawl construction that ultimately resembles an arrowhead. This effect is emphasized by colorful stripes. The classic Arrow shawl is knitted using garter stitch.

However, not everyone knits, just as not everyone crochets. That is why, in the Knitting or Crochet? Crochet or Knitting? series, I present a crochet Arrow shawl worked in the moss stitch.

Any yarn may be used; adjust the hook size accordingly.
The size of the shawl can be adapted to individual preferences.
