1) What yarn (that you don’t have/haven’t used) would make your stash “complete”?
Let's see, I would have to say some of the garnstudioEskimo or Silke alpaca. I have never tried it and would love to.
2) What yarn do you never want to be without?**
For this one, I would say cascade 220. I love all the different colors. I would also add Elsabeth Lavold Silky wool
