A short note comparing how weft colors are handled in ordinary weaving, in Gobelins tapestry, and in Navajo weaving. The author explains that a Navajo weaver fills in areas of color with whatever length of yarn she has, producing irregular zigzag boundaries and small scattered vertical slits, and beats the work down with a stick. A photograph shows two blanket weavers at a loom, captioned as from "The Painted Desert," San Diego, California.
