Crafts - my favorite yarns and yarn stores

Like many people I love natural yarns and fibers - merino, cotton, the more the better. Somehow most of my stack contains Lana Grossa yarns but I have recently - thanks to fellow enablers... oops, I meant knitters ;-) - found some awesome stores and yarns and am trying NOT to spend too much money since my stash is big enough for now.

So in no particular order and mostly for myself as a kind of bookmark...

• Lana Grossa
• Dragonfly Fibers (not ordered yet but got some things on the wishlist)
• Colour Adventures (stashed but not used yet)
• String Theory Yarn (stashed but not used yet - how could I resist, being a geek?)
• Wollmeise - (ordered via a friend)

Look at these beauties... (Colour Adventures and String Theory) <3

Are there any other stores and yarns you think I should know about? Recommendations welcome!
