I have another pattern download for free on Ravelry, again made to fit Wool-Aid requirements.
I really like the simplicity of this stitch, so much so that I am knitting a 34" around sweater for Wool-Aid using mostly this stitch pattern. I have seen it by a few other names, and used in many pattern books, but it reminds me of long thermal underwear so that is the name I use.
The pattern is available HERE
-80 yards Worsted weight yarn (sample used Knit Picks Wool of the Andes Tweed in ‘Indigo Heather’)
-2 stitch markers
-Gauge: 4.5 stitches per inch after blocking, in pattern stitch.
