Sunday is our thinnest yarn made from 100% merino wool. It is a perfect basic yarn: thin and not superwash treated. The yarn can be knitted with single strands or double strands. It also works wonderfully when combined with Thin Silk Mohair. Merino wool is not only excellent for thermal insulation, but it also wicks moisture away from the body due to the structure of its fibers and retains heat even when damp. Wool can absorb up to 30% of its own weight in water before it feels wet. Our suppliers guarantee that our wool does not come from sheep that have been subjected to mulesing.
