I've been knitting for about a year or so and I've never used any nice yarn. Partly because the LYS near where I was living is stinky and partly due to cost.
Well...I just started a new project with Suri Merino from my new LYS and guh....oh my, heaven running through my fingers. It's sooo soft and delicious. And this isn't even top of the line yarn or anything! It's just not RedHeart/Encore/etc. Yummmmm.......my poor wallet is in for a shock.
