A July 1938 installment by Nellie Sargent Johnson in Handweaving News on turning unit-block pattern designs into actual four-harness overshot threading drafts. It explains the four pattern blocks (1&2, 2&3, 3&4, 4&1), how adjacent blocks overlap by one thread, keeping plain-weave alternation correct, and breaking up long skips with single threads or shorter blocks. It also covers weaving as drawn, loom tie-up for treadle and jack looms, weaving on opposites, accidentals, and fitting a draft to a given number of warp threads. A page of figures gives the key draft and threading drafts Nos. 3-9.
