An article from Master Weaver (Z-Handicrafts, Fulford, Quebec) explaining how a handweaver analyses a single-layer fabric sample. It describes marking one repeat, making a draw-down on graph paper, identifying identical warp columns to derive the threading, and deriving the tie-up and treadling together. It also covers counting the frames needed, rearranging threading and tie-up into standard forms, and recording yarn and finishing data. Illustrated with draw-down and draft figures; it closes by announcing follow-up articles on short analysis and three-dimensional fabrics.
