A collection of pattern leaflets by Mary Meigs Atwater for the Structo Mfg. Co. of Freeport, Illinois, giving threading drafts and lever-by-lever weaving directions for the Structo 600 four-harness loom. It opens with a group of small threadings (twill, dornick, bird-eye, goose-eye, Bronson, Ms and Os, huck), then covers numbered coverlet-style patterns such as Honeysuckle, The Diamond (with Holland Chain and Rose in the Wilderness treadlings), Monk's Belt, Lovers' Knot and White Rose, a Summer and Winter arrangement, Double Chariot-Wheels, Double Bow-Knot, Nine Snow-Balls, Governor's Garden, Queen's Delight and Solomon's Delight. Each gives heddle counts per harness, thread counts, tabby sheds, and notes on colors and uses.
