June 1955 issue of the Shuttle Craft Guild Handweaver's Bulletin (Portfolio Edition). It covers the Spot (Spot Bronson) weave for linens, with drafts taken from old Colonial American homespun linens, including a four-harness diamond, a five-harness diamond and a dresser scarf/table cloth pattern. It continues the 'Understanding Drafts' series with an explanation of the Profile draft and 16 substitution units (keys) for unit weaves such as Summer and Winter, Atwater-Bronson lace, Bateman weaves and Warp Pattern weaves. It ends with a four-harness modern linen dress fabric variation of the Spot Weave. The Portfolio pages carry fabric samples and a Colonial Heritage 'Distaff' card.
