Some of my stash

I recently took out all of my stash to judge if I had enough yarn for a particular project (Lyra’s garter stitch coat from the Golden Compass, see here to see how that worked out). It is now covering my entire dining room table, all the chairs and part of the floor.

How did this happen to me? I can’t believe how much yarn I have, when did I get it all? Was I there? Did I agree to this? Will my renter’s insurance cover thousands of dollars in knitting supplies?
