This is a Brioche pattern using 3 different colors, but can be knit with just one.
Random double striping was used in the featured scarf, which is not included in the chart, or instructions. Once you become familiar with the pattern, you can choose to insert some extra striping wherever you want it.

where I post stitch patterns, from time to time.

Special thanks to Nancy Marchant for a wonderful class in Brioche Knitting!

Errata - There should only be 4 columns in the pattern chart. Delete column 4, or download again and get the corrected version. The written instructions are correct. It is a 2 stitch pattern repeat.
