This cowl was inspired by the "Totally biased" pattern. Mine does not have purl rows. Handspun is Mixed Bluefaced Leicester.
(edited to correct my "recipe"; thanks greenmtngirl for the note)
I followed this "recipe" until almost all the yarn was used up:
cast on 40 stitches for handspun sport to aran weight
row 1: k1, k1fb, k to last there stitches, k2tog, k1
row 2: k2, p36, k2
three needle bind off
Cast on. Carry on. Have a great weekend.
