ZOMG! The scarf that would never end! Luckily I discovered on the Ravelry forums, the section ratios were 1/5, 3/5, 1/5.
Instead of using stitch markers, that I kept losing or they got in the way, I purled the stitch to be dropped on the knit side & then knit the stitch on the purl side. It went much faster then!
