Hold this yarn with another wool to make a cloud-like fabric. 

Mohair-silk lace is a single-ply strand of absolute luxury.

It's a laceweight single-ply blend of soft-as-a-cloud kid mohair and silk, and I adore holding it together with another yarn to create sweaters and shawls with a perfect halo.

Hand-dyed mohair-silk lace takes sweaters to a new level of beauty. 

You can take virtually any pattern that calls for a worsted weight yarn and use mohair-silk lace a fingering weight yarn. It blooms and fluffs, so that the resulting fabric is incredibly resistant to pilling. It also marls and softens color to create completely new shades and tones.

Is it more expensive to knit a sweater like this?

Actually, no. Using this yarn plus a fingering weight yarn (to get a worsted weight gauge) is about the yardages of two worsted weight skeins. Two skeins = two skeins. (You can read more .)
