Lesson 10 of the Master Weaver series 'Problems in Teaching', on drawing profile drafts for weaves without clear units (overshot) or with very short units (swivel, plain spot weave). It describes three methods: choosing blocks divisible into equal groups, one square per heddle, and an approximate profile with one square for a range of heddles. Examples show threading drafts with matching profiles for swivel, overshot, barley corn and Bronson spot weave, and the text notes that the third method distorts the pattern.
