Here's the V Day Yurt by knitting artist Lisa Anne Auerbach. 
It is 10ft in diameter, knitted in bamboo yarn and  has just been shown at the Hammerstein Ballroom NYC, in celebration of 10 years of VDay. 
Lisa was comissioned to knit a vagina, but she took it a stage further and knitted a yurt where you are 'Welcomed to the Wetlands to bow down and worship the Vagina Queens'.
What a marvelous piece of knitting. 
We wish we were there.
