A short pamphlet by Helen Daniels Young, written for novice weavers, explaining how to weave an overshot pattern "on the diagonal" by reading the design-spaces in the warp rather than following a written draft or treadling directions. It includes a practice project (a short warp with sett, threading plan and materials), step-by-step instructions for squaring blocks along the diagonal, and a weaving theory section covering drafts, tabby, pattern harness pairs, blocks, threads-in-common, half-tones, units, and 2-block (Swedish, "on opposites") overshot. The last page lists other Helen D. Young monographs and publications available from Two Cape Cod Weavers.
