Lenja Soft is the softest baby yarn I have felt in a very long time, possibly ever. This yarn is incredibly cozy yet light and has a terry cloth feel when worked into fabric. This is a great choice for a treasured cuddly baby blanket or anything that will be worn against baby's skin. Lenja Soft is 100% Polyester and each ball weighs 25 grams and has 93 yards of yarn. Suggested tension is 20 sts by 29 rows = 4 inches on a size US6 needle. Machine washable.
