A short dictionary entry defining the two-ply carpet, a double-web fabric in which two sets of warp and weft interchange to produce reversible patterns in different colors. It covers the materials (worsted and wool), the use of treadles or Jacquard control, and the alternate names Scotch, Kidderminster and ingrain. It also mentions three-ply or triple-ingrain carpet. Includes one small illustration (Fig. 6840) of a double cloth section.
