Here's a pattern that I wrote for one of my favorite hand dyed yarns -- Woolbearers' Alfresco.
Alfresco Brioche Cowl
YOSL1 – Yarnover and slip 1 at the same time (it will appear as if you have made two stitches)
Cast on 48 stitches. Put in stitch marker to note the beginning of round. Purl one row.
Set up row: *YOSL1 , K1; Rep from *
Round 1: *Knit the next stitch with its YO , YOSL1; Rep from *
Round 2: *YOSL1, Purl the next stitch with its YO; Rep from *
Repeat these two rounds until you have enough yarn to bind off.
Bind off very loosely.
The middle two stitches are composed of the yarnover and slipped stitch. They will be either knit together or purled together, depending upon which round you are doing.
