Report by Kathie Frank on a March 1977 Weavers Guild tour of the North Central Wool Marketing Corporation ("Woolgrowers") in Minneapolis. It describes how fleeces are received, graded by eye for fiber diameter, staple length and condition, baled, and lab-tested for grease and dirt loss, and how the cooperative markets wool. The page also carries a Library News column listing new frame loom and off-loom books and updates on the guild library card file.
