An International Correspondence Schools instruction paper (Serial 507) on the construction of satin weaves and weaves derived from them. It explains how satin bases are chosen, warp- and filling-flush satins, irregular 6-end satins, and double satins, and includes a table of satin orders for 5 to 12 ends. It then covers satin derivatives, granite weaves, basket weaves, warp and filling ribs, unequal ribs, corkscrew weaves, and honeycombs. Most pages carry small drawdown figures, and practice exercises follow two of the sections.
