I got this great camel colored merino wool at the Sheep and Wool Festival. You can see the beginnings of a scarf I am making using a Shadow Cable type of stitch. If you want to knit along, here is the pattern:
Cast on 44 stitches.
Row 1: Slip 1 and then purl across (all wrong side, odd numbered rows)
Row 2: Slip 1 and then knit across.
Row 4: Slip 1, knit 1, C4B, (K4, C4B) across to last 6 stitches. K6.
Row 6: Slip 1 and then knit across.
Row 8: Slip 1, K5, C4F, (K4, C4F) across to last 2 stitches. K 2.
Repeat Rows 1-8.
