Folio 28 from the Osma Gallinger Tod Studio explains the swivel weave, in which pattern blocks appear as colored tabby blocks on the cloth surface with floats on the back. It describes Basic Swivel (three blocks on harnesses 2, 3 and 4) and Two-block Swivel (harness 4 used for accent warps), with four 240-thread drafts, tie-ups for jack and counterbalanced looms, and treadling directions. It also shows how to weave overshot patterns and Summer and Winter as swivel, with the overshot pattern 'Salem Streets' by Helen D. Young as a worked example, including warp plans for fine and coarse settings.
