This rectangular shawl is made with a Whirl and a Whirlette. You can also use any fingering weight yarn.
The size is very easy to adapt. Simply add stripes to make it wider, or add/subtract multiples of 12 stitches to adjust the length.
The ends left by the color changes are used for the fringes, so you only have 1 little yarn end to sew in.
This pattern includes written instructions as well as a chart.
