This one is a bit different because I felted it a bit.
It's 166 stitches across, add a stitch slightly less than every row, 105 rows. Each color band is 5 rows. Do perling on the last band to keep it from rolling. 4.50mm needles
I used 4 skeins of Malabrigo worsted wool (more like 1.5 skeins of each color)
Sewing in elastic for the waist
