Example 1: natural cotton and red wool. Inscribed Rebecca T. Scott 1837 Jefferson Co. NY. Woven by Harry Tyler (American, 1801-1858).
"The best spinner in the neighborhood took great pride in producing smooth, even thread for the Tyler coverlets. Tyler's coverlets became known as "two-ply" by which undoubtedly is meant double cloth, woven in two colors, blue and white or red and white.
The dyeing was done in a small building at the rear of the house and he used indigo for blue and cochineal for red. He purchased all the dyes from Elisha Camp. A large brass pot was used for dyeing and the weekly chore for the boys was to keep it clean and brightly polished by scrubbing it with salt and vinegar and old house brooms. He charged $2.75 for weaving one coverlet or $2.50 for more than one in the same weave. An additional charge was made for dyeing wool scarlet from the expensive cochineal."
