Help me substitute yarn for this project

I want to substitute something from knitpicks for this project: http://www.sheepinthecity.prettyposies.com/archives/000079.html

The yarn mentioned is a bit out of my price range!
Any ideas, my lovely knitpix experts??? I think I really want varigated yarn to bring out the st pattern, but having a hard time finding the right thing at knit picks!

Hellllllp.

Andean Silk?

THe only thing is you arent going to get the GAWGEOUS colorways that the Manos has…although, you COULD try choosing THREE colors and knitting with 2 held together, alternating WHICH two you hold together throughout the scarf? Then you’d need a thinner yarn…maybe Andean Treasure then?

Manos is a heavy worsted weight. If you’re going to sub by using two strands of a knitpicks yarn, I suggest buying one ball of each first and testing them for gauge.

Otherwise, check out the Yarndex list of heavy worsted wool yarns.
