A short article from Master Weaver (Dec. 1951) on working out all the possible variations of a four-block pattern (three pattern blocks plus ground). It explains a notation for combining blocks and presents grids of small profile and drawdown diagrams showing 64 symmetrical variations woven from one threading. The final page begins a note on weaving terminology, taken from the 'Encyclopedia of Hand-Weaving', discussing the word 'harness' and its synonyms (heddle-frame, shaft, leaf, heald). The scan opens with the end of an unrelated discussion about weavers' motivations.
