A short web document by Allan Wentink explaining Hadamard matrices (square matrices of +1 and -1 entries) and how they can be used as weaving tie-ups. It covers definitions, properties, equivalence operations, and a table of the number of distinct matrices by order. It shows normalized matrices of order 1 to 16 as black-and-white grids, demonstrates turning H4 into a warp-surface twill tie-up, and ends with an H16 tie-up and drawdown.

A short technical paper showing how to quantify warp tension using Reid Bryson's homemade tension meter, a ruler, and a scale. It derives a formula from the deflection of a warp end under a hanging weight (T = WL/4H) and its inverse for finding the deflection needed for a target tension. Worked examples show how a weaver can record a tension and transfer it to another loom or weaver. It notes limitations such as stretchy yarn and the added weight of the meter.

A short mathematical paper expanding on a method from Masson and Roussel's Shaft Weaving and Graphical Design for making symmetrical profile designs with independent blocks. It explains that a profile threading, a treadling "as drawn in", and an involute tie-up together give a symmetric result. It tabulates the number of involutes for two to eight blocks, with the recursion formula, and illustrates all 26 involutes for five blocks. A second figure gives the corresponding profile drafts.

A short mathematical analysis showing that any two four-shaft overshot threadings of the same length can be blended onto eight shafts, and that only two mappings accomplish this. Using a digraph notation that pairs a shaft from draft I with a shaft from draft II, the author works through the twill-order rule of overshot threading in tables. The result is a summary table giving which eight-shaft mapping to use based on the first warp thread of each draft.
