Well it is for me, but I'm not that experienced a knitter.
It is bulging on the left cuz I made an increase where I shouldn't have (twice!). Will leave this as a reminder to myself to be more careful. I also made one less garter ridge in the first section, urk!
It is fun and challenging for me to make this, cuz it requires more awareness than knitting skill. It's just knit, purl, inc and decreases. But I have to keep my wits about me (and some days it seems, those wits take a nap!) Much fun though, and I will wear this scarf in dark, gloomy wintertime, when a burst of sunshine is needed.
Every other row changes color, and there are 8 ridges of garter stitch, separated by 6 rows of stockinette, alternating orange and yellow yarns. The increase/dec rows are only on the right side. So I have to remember:
inc or not row
change color every two rows
work 8 ridges, then 6 rows stockinette
when beginning a new garter st section, begin with the color opposite to the one you ended the last section with.
Complicated? or Easy?....you decide.
