An International Correspondence Schools instruction paper on the work of a textile mill designer and the mill's sample-making department. It covers the designer's duties, the equipment of the designer's room and sample weave room (yarn and cloth testing machines, reels, sample books), how new styles originate, and how trial and selling samples are made. Procedures described include blanket warps, warping on pegs from a creel, beaming, drawing in, weaving, and tying over warp ends to get more samples from one warp. The one page marked as a draft is a set of color-order specifications for six warp patterns, not a weave draft.
