Weaver's Guide to Wool Yarn

source

Liz Gipson at Yarnworker gives weavers some valuable information on selecting wool for weaving. She reminds weavers that most of the yarn rules regarding looms apply to looms with shafts. Those rules may not apply to the rigid heddle weaver since this loom doesn’t put as many demands on the yarn.

She states that in general, using the simple pinch and pull test will allow a weaver to determine if yarn is strong enough for warp. Virtually any yarn can be used for weft, however, weavers still may want to consider how well it will wear over time and under the rigors of its intended use.

Liz's post, A Weaver's Guide to Wool Yarn, is a good source for rigid heddle weavers.
