A two-page Swatch Page article from Minnesota Weaver on M's and O's, a linen weave of alternating plain-weave and rib blocks with four-thread skips. It gives threading, tie-up and treadling drafts for four samples, a short theory section, materials (10/2 cotton perle, 7/2 wool, 10 dent reed sleyed double), and comments on variations. It closes with a bibliography and a question about the origin of the name.
