A 1956 Master Weaver article that distinguishes true multiple warps (separate warps on one or more beams, as for velvet and tissue weaves) from mixed warps of different yarns. It explains how to work out the sett for mixed yarns by averaging counts, converting to yards per pound, and how to test yarn elasticity. It also describes a homemade tension box built from a hardwood block and shuttle bobbins, and gives advice on beaming, threading and sleying mixed warps.
