Dyes for homespun clothes?

Barkeater said:"One question I have is whether "frontier folk" were actually attempting dyeing for home made personal clothes on the farm? Or was all the colored fabric an imported item?"

It's my impression that they did.

William N. Blane: _An Excursion through the United States and Canada, during the Years 1822-3 by an English Gentleman_. 
Describing the daily activities on a farm in western Kentucky:

"Besides the labour of cooking, cleaning the house, &c. the American farmer’s wife makes every article of clothing for her whole family. The men wear a sort of coarse cloth made of cotton and wool. The cotton is grown upon the farm, is picked, spun, weaved, dyed with the indigo that also grows on the farm, cut up and made into clothes by the female part of the family. The wool of their own sheep furnishes materials for the mixed cloth, stockings, &c. All the linen for shirts, sheets, and towels, is also made at home from their own flax."

Mentions of dying show up in strange paces. In the spring and early summer of 1775, James Nourse, Sr. traveled with a small party by dugout canoe down the Ohio River to the first settlement in Kentucky, Harrodstown, on the Kentucky River, and kept a journal. Here's part of his journal entry for Saturday 13th May. "Tom finished washing my linen and dying my Hunting Shirt."
