An ingrain carpet was a flat, woven, reversible wool carpet made of yarn dyed before weaving. The wool was then woven on a jacquard loom accommodating up to six colored weft threads. Ingrain carpets were popular in middle-class homes in 18^th and 19^th century America; in many middle class homes of the 1800s at least one room had ingrain carpet. 

This ingrain carpet runner was 16 feet long and 33 inches wide; woven with red, green, brown and natural color wools. The wool was sheered from sheep raised by by Abigail Safford in Pompey, N.Y. about 1837.  The weavers were Joseph J. Davidson and John M. Davidson. The original receipt reads:

Rec.d of D.D. Safford fifteen dollars and thirty one cents for weaving and colouring an Ingrain Carpet. Ithaca Aug. 6, 1841 - Joseph J. Davidson and John M. Davidson.
