We’ve got gradient kits over at Three Fates Yarns. I’ve taken my most popular colorways and turned them into gradient kits of 2.5 skeins/kit. The yarn is Terra Sock, a high-twist 3ply blend of Merino and nylon yarn. It’s wonderfully bouncy and durable. The put-up size is large which makes it very flexible. Other than making baby sweaters for twins, you can easily weave or crochet with this amount of yarn. It also makes wonderful shawls and cowls. Add a contrasting neutral like woodsmoke and you’ll have the perfect sweater.
