Wool is symbolic of Spiritual Protection. Lamb was sacrificed by the Jews at Passover, Christ was the Lamb of God so the spiritual significance of wool is obvious. Wool has, from earliest times, represented warmth and protectiveness. Nowadays it particularly represents gentleness and mothering. How we interpret wool depends on whether the image we have is of lamb's wool or of knitting wool. Lamb's wool may stand for blurred thoughts and feelings. We have not really sorted our thoughts out. ?Pulling the wool? over someone's eyes, though generally accepted as being devious, can also be a protective act. Also consult the entry for Knitting.
