"RESILIENT" SUPERWASH MERINO WOOL SOCK YARN - our signature sock yarn! After years of using various sock yarns, I had the mill spin up this custom yarn for us, which embodies everything you'd want in an ideal sock yarn:

•4-ply : Results in round, defined, beautiful stitches. The more plies the better for items that will get lots of wear like socks. Your projects will last and last with very little pilling, strand breaking or wearing thin.
•BOUNCE FACTOR - this yarn is BOINGY! It has a ton of memory, or "resilience" (thus the name), which is ideal for socks since it stretches but bounces right back to its original length. Perfect! 
•Fingering Weight: Perfect for hand-knit socks, but also virtually any other accessory you want to make, like hats, scarves and shawls, mittens, including baby and kid items. Wonderful for sweaters and other garments or even blankets! Sock yarn is so versatile and well-loved by many yarnies.
•Superwash Merino Wool = super soft, super fine wool. No itchiness here! Machine-washable! Hand-washing keeps your items looking the best the longest, but no worries if your socks accidently get tossed into the washer and dryer. They'll be just fine and won't felt or ruin. Whew.
