A 1959 instructional booklet by Mary E. Black, published by Lily Mills, on understanding and handweaving Scottish tartans. It explains the difference between a plaid and a tartan, the clan and district origins of setts, and the block system for threading and treadling setts on a 2/2 twill. Step-by-step projects (Menzies, Buchanan, MacLeod, Johnstone, MacPherson, Mackintosh, Dress Stewart) give materials, sleying, warp setts, block order and finished sizes for place mats, napkins, scarves, skirts and dress lengths in Lily cotton and wool yarns. Also covers beating to keep a 45-degree diagonal, selvedges, and finishing.
