Oooo... I just noticed this on Ravelry, it didn't come into my inbox.
1) What yarn (that you don’t have/haven’t used) would make your stash “complete”?
Oh this isn't any easier to answer! I would love to try some Noro though I'm not sure which one, Silk Garden, maybe? It's the one that has a long colour change. There are just so many beautiful yarns out there, the vast majority of which I've only seen on the internet... I just love all the variegated ones in delicious colours in delicious yarn mixes. I cannot answer this question!!
2) What yarn do you never want to be without?**
Ooh, I'm not much help, I can't answer this one either. Variegated sock yarn, I think... I think!
