Oh my gosh Midnight .... who WOULDN'T want to get yarn from YOU !!!!!!
I don't have anything "worthy" right now ... but if I get to go to Portugal in June, I am hoping to come back with a BIG STASH and would love to share. I am still having problems researching exactly where to go and what to ask for.
http://www.portugalvirtual.pt/0/0139.html has a list of yarn mills. I have not found any information about LYS's or buying "mill ends" or even what kind of yarn they make!
