I saw this on Stephanie Japel's blog, and I immediately joined the Ravelry group and casted on for my squares:
I made two in Araucania Magallanes, 6x6".
Then I read the instructions: 9x9" superwash.
Uhm. Do you do know if any worthy cause that accept 6x6" non machine washable wool squares?
I am going to look through my stash again .......
