I saw this knitted womb on the website Knitty.com today. The subtitle on the website is "purls of wisdom." :)
The knitter, K Carroll, says, "Human anatomy is pretty amazing, but not always pretty. My interest in anatomy coupled with the Blythe dolls phenomenon somehow combined in my imagination to produce a cute, cuddly uterus doll."
