Dryad Leaflet No. 85 is a beginner's instruction booklet on weaving rugs with string warp and wool weft, covering three Dryad devices: a simple rug frame, a rug loom with a reed and screw tensioning, and a foot power rug loom with heddle frames and treadles. It explains warping, making sheds with leashes, weaving technique, joining wool, and keeping edges even. It also covers pattern weaving with colour bands and slit-avoiding methods, a sampler rug chart, knotted pile rugs, colour choice, finishing fringes, and a table of material quantities.
