A one-page Questions and Answers column by Mary M. Atwater answering two weaver questions. The first covers causes of poor left-hand selvedges, including lighting, shuttle habits, uneven warp tension and loom frame misalignment. The second explains why the warp should not always be stretched very tight, especially on jack-type looms, where it lifts the harnesses and spoils the shed. An errata note corrects the author credit of the previous issue's "Coverlet Samplers" article to Marguerite P. Davison.
