A June 1940 Handweaving News article by Nellie Sargent Johnson on designing a two-block pattern key draft and converting it into several four-harness threadings. It explains how to draw the pattern from the key draft and gives threading and weaving instructions for Colonial overshot, single and double M's and O's, summer and winter (two ways of writing), Five and One, Matta (Mattor) rug weave, and a two-block lengthwise stripe pattern. Page 3 carries the threading drafts and tie-ups as Figures 3 to 8.
