Fred L. Copp describes a method for designing new four-harness overshot patterns by threading an experimental warp with three or four different drafts and weaving them side by side. He recommends weaving each block in both "star" and "rose" fashion, using leftover yarns and a different color for each pattern, and keeping records. He illustrates the method with a sequence of figures (Figures 1-6) that enlarge a butterfly-wing motif derived from Big Pine Burr, Honeysuckle and a Swedish pattern, and argues weavers should adapt Colonial drafts rather than just copy them.
