A two-page installment of E. Bittner's series on the construction of weaves, dealing with figured weaves. It explains how inserting or removing risers in plain, rib, twill and satin grounds lengthens or shortens floats to produce figured effects. Figs. 493-507 are drawdown diagrams with captions giving the ground type, repeat size and whether risers were added or removed.

A single-page installment of E. Bittner's series on the construction of weaves, covering color effects. It explains how to work out in advance the look of a weave with colored warp and filling threads, including finding the pattern size as the least common multiple of the weave and color repeats, and drafting on cross-section paper. Figures 517 to 526 show color effects on plain weave, such as cross stripes, warp stripes and block effects, each with a caption giving the color order.

A single page from E. Bittner's series on the construction of weaves, printed in Textiles. It presents weaving drafts for figures 536-548, each with threading, tie-up, treadling and drawdown, showing twill constructions in dark and light thread arrangements. Captions identify 4-leaf and 6-leaf filling, warp and balanced twills, broken twills, zig-zag twills and modified warp twills.

A single page from E. Bittner's series on the construction of weaves, showing figs. 527-535 with their captions. It covers color effects on plain weave, made by offsetting the weave with warp and filling arranged 1 light 1 dark, and introduces color effects on twill weaves, with 3-leaf warp twill and 4-leaf filling twill examples. The page mostly consists of drawdown-style drafts with short explanatory text.

Two pages from Textiles (vol. 15) containing part 4 of E. Bittner's series on the construction of weaves, which covers motifs developed with 3-leaf warp and filling twills and their color effects (Figs. 549-550f). The same pages also carry a section of John Reynolds's 'The Practical Fixing of Cotton Looms', on timing the still box motion and adjusting the 6 and 1 box motion.

Two pages from Textiles (pp. 16-17) carrying a part of E. Bittner's series on the construction of weaves. This part covers color effects on satin and other weaves: stripes and checks made by arranging colored warp and filling threads on satin, corkscrew, crepe, basket, radiating twill and thousand-square weaves (Figs. 551-567), each with a draft. Page 17 also has an unrelated article by Dr. Louis J. Matos on identifying textile fibers under the microscope and with chemical tests, covering wool kemps, natural and tussah silk, and a wool/silk reagent comparison.
