A short critical article from Master Weaver arguing that plain rag rugs (catalogne) are economically and aesthetically poor and wear badly. It explains that the usual fine, closely set 16/2 cotton warp is exposed and breaks down under foot traffic. It recommends a strong, open warp (heavy carpet warp or 8/3 linen at no more than 8 ends per inch) with a twisted weft, hard beating, and locked wefts for patterns. It concludes that heavy cotton rug filler is a better choice than cut rags.
