They have a factory store onsite that occupies the original woolen mill (Johnson no longer weaves its own cloth, but has it regionally sourced) that is at the top of my shopping list... or you can buy the stuff online or through your local, right thinking hardware store. Big in Japan as they say..
Have saved a ton of images via eBay over last 2 years but first a few photos from a tour of the mill by TobyGrubb, reproduced with permisson.
