Rabbit Tracks scarf
All the increases are on the first pattern row but only half the decreases; the other half of the decreases are on the second right-side row, bringing it back to the original stitch count. If you end the piece after the second pattern row, I haven't had the end selvedge come out very wavy compared to many feather-and-fan variants--some, though, but it depends in part on the yarn and the gauge.
I do think as a stand-alone pattern for a scarf it looks better with an extra stitch at each side, but at the time I posted the pattern I was working with a very small amount of pure angora and trying to stretch it as far as I could go.
Glad you all enjoy my Rabbit Tracks, and thank you! And thank you for the heads-up that people had questions about it.
