Yarn Possibility?

KnitPicks just came out with a bulky wool of the andes handpaint and solids. I wonder if this would be a less costly yarn alternative. The pattern is very easy to change for different gauges. Simply knit the inner circle until it is the correct width for your own arms and knit the outer circle until it is the desired diameter.

I bet it would be quick - though some may not like added bulk. I love this shrug!
