A short article from Master Weaver explaining the M's-&-O's weave, its tendency toward weft slippage, and the lack of solid tabby in the classical draft. It shows that M's-&-O's can be woven on nearly any threading by alternating opposite treadles, compares overshot, crackle, summer-and-winter, huckaback, Bronson and Swedish lace, and gives two worked examples (huckaback and Bronson) with profiles, warp sett, threading, tie-up and treadling instructions.
