Merino wool yarn
Merino is wool from Merino sheep. Compare fineness, yarn structure and the care treatment before substituting it for another wool.
Match the fabric to the project
A fine wool strand can make a soft fabric, but tightly spun sock yarn and a lofty single make different surfaces. Include the project’s ribbing or cable in the swatch.
Finish a sample first
Superwash is a treatment, not a stitch gauge. Use the exact band directions and check the fully dry swatch for growth and pilling under the intended wear.
