okay here goes,
Cast on 81 stitches
row 1 - purl
row 2 - p2, *k2tog, yo, p2 * (repeat from * to * to end)
but I end up with 3 stitches left. I am short one stitch in order to finish with the p2. Does this make sense? The pattern is for an even number of stitches but they have you cast on an odd number. I don't understand this.
