"Wool, The Original Miracle Fiber" -via Bemidji Woolen Mills
The Bemidji Woolen Mills was founded in 1920 by father and son Ira Preston and Ira Hubert Batchelder who set out to produce high quality woolen apparel for the early logging era in Minnesota and surrounding states. The market area was mainly Northern Minnesota and Northern Wisconsin.
Just discovered Bemidji via V.B. Holcombe and Sons. Same sort of resource as Johnson Woolen Mills I guess. Data mining below. (I want that hat...)
