photo shows Sport weight, size US 5
4x4 inch swatch = 11 stitches, 52 rows
This stitch pattern has a lot of horizontal stretch, but because it is a brioche stitch, the stitch is compacted vertically.
The use of 3 alternating colors, helps add visual interest, but this pattern can be done with one yarn, as well as a mixture of many yarns.
For making a long scarf, cast on at least 211 stitches, or any larger uneven number and leave ends free (as fringe). In this way, you can use this pattern as a stash buster.
This chart can be used to see how 3 different yarns [CA (color A), CB, and CC], used alternately, only repeat every 7 rows.
The pattern is started on the wrong side (ws). This is just for use of the chart, as the pattern is reversible.
Cast on using the Italian 2 color CO method http://www.youtube.com/watch?v=777ow6z5S0E
Set up Row 1 (ws): Using CB (k1, sl1yo) to last stitch, k1, UNDO - the slip knot, that was used to hold the yarns together (so you don't accidentally use it as a stitch).

Row 3 (ws): Using CA, (brk, sl1yo) to last stitch, brk
Row 4 (rs): Using CB, repeat Row 2

Row 6 (rs): Using CA, repeat Row 2
Row 7 (ws): Using CB, repeat Row 3

Bind off (ws): Using CC, and the Kitchener Stitch, bind off the brks as knits, and the single stitches as purls.
