This charming baby sweater set is hand knit with a blend of wool and alpaca yarn: 60% wool and 40% alpaca. The yarn is locally raised/milled and feels as soft as pure alpaca. The set comes in two sizes (0-3month and 3-6 months) though other sizes can be custom ordered at no extra charge. It comes only in natural white, which is an off-white. It hasn't been bleached or spun/milled with chemicals. This delightful baby sweater set is luxurious, light weight, warm, and super soft without the extra cost of alpaca. This makes a unique and elegant gift for a new baby!
