A nineteenth-century American manual for mill designers on working out fancy cotton and woollen cloth from a sample of the finished fabric. It explains how to pick out a draft from a sample, reduce drafts, and calculate wool quantities, spooling, heddles for each harness, and reed numbers. Fifty numbered drafts are described one by one with their yarn sizes, colours, warp counts and harness arrangements, and the book closes with tables of yarn sizes for wool and cotton. Nine plates at the end show the straight drafts, drawing-in drafts, reduced drafts and loom chains.
