Alpaca & Friends: Choosing the Right Blend

Combining alpaca’s rich, silky drape with the Merino’s bounce or silk’s luster can allow us to build our best knits yet.

The soft silkiness of a great alpaca yarn is irresistible. Alpaca can be as fine as Merino, but depending on how it was spun, it might behave more like silk. As Jacqueline Harp explains, alpaca fiber has elasticity but limited memory due to its structure. Where Merino has a tight crimp that creates springy bounce, fine alpaca is more likely to have a gentle wave. This creates more drape and less memory.

This means that if I knit it into a loose stockinette stitch, it will be beautiful, but its drape will dominate. If I knit it into seed stitch, cables, or slipped-stitch patterns (such as the Timberlane Cowl), I can build structure into the fabric. But what if I want drape and memory?

Blends for Different Reasons and Seasons

Alpaca, like so many fibers, can be nudged toward different fabric effects when combined with other fibers. The first alpaca blend I fell hard for was a 50/50 blend of alpaca/silk, which shifted the fine alpaca fiber toward the drape and sheen of silk. This changes the dye effect and the surface reflectance—swoon! However, a 50/50 blend will still tend to have a bit more of a wooly feel and plumpness than a silk yarn.

Alpaca/Merino blends will shift fine alpaca in the other direction—toward loft, elasticity, and matte finish. These are great for sweaters and socks and anything that needs to be lighter weight and hold its shape.

And there are many more alpaca blends. Manos del Uruguay has a fab alpaca/pima cotton blend that combines two soft fibers into a yarn that would be great for a divine warm-weather wrap. We are lucky to have so many natural fibers near to hand!
