A short 1958 notice from Master Weaver describing a two-disk rotating scale that gives the sett of warp (ends per inch) without calculation. The central disk lists 20 typical weaves and the outer disk lists yarn counts in yards per pound, from 100 to 90,000. The article explains how to assemble the printed version, the range of setts it covers (5 to 158 per inch), and how to extend the yarn conversion table. It ends with prices and an ordering address in Fulford, Quebec.
