Went to this shop; Thought I had died and gone to heaven. (It's been in busines for well over 50 yrs.) Extremely helpful. As wonderful as the web site is, the shop is wonderful. Just wish I lived closer...
When you phone in advance, it is usually possible to have a tour of the mill which has been operating since the 1840s. The tour alone is well worth going way out of your way. The shop is just a bonus.
