A one-page article from the Multiple-Harness Weaver column presenting a "hollow square" pattern made by combining two blocks in the tie-up. The top draft comes from Ester Perheentupa's Finnish multiple-harness book Kutokaa Kuviollisia Kankaita, with M's and O's on the four center harnesses and a third block added by front and back harnesses. The same pattern is then redrafted in the unit system described in the February Shuttle-Craft, with a compacted version that gives twice as many pattern blocks at the cost of a true tabby. Several drafts on six and eight shafts are shown with border, balance and pattern repeat labels.
