This pattern is mostly of my own devising, but it was inspired by a similar free pattern provided by KnitPicks. Gauge is not really critical for the success of this stole.

CO 40 stitches with US size 15 needle.
Switch to US size 10 needle
Row 1: Knit across
Row 2: (K1 YO2) repeat until 1 stitch remains, K1 Row 3: Knit across

Repeat Rows 1-3 until stole measures 66".
Bind off loosely knitwise with US size 15 needle.

The end product is roughly 66" long and 10" wide. It took 2 skeins an a bit more from a third skein to match my wingspan -- I have quite a bit of the third skein left to play with. You could probably get very close to 60" with only two skeins.

I like working with Ibis a great deal. Very soft and it didn't stick to my Denise needles. The only thing that I had to watch out for was splitting the fuzzy part from the binding strand.
