Some weavers prefer the backstrap method of weaving, where one end of the warp was tucked into, or wrapped around the weaver's belt, and the other is looped over a toe, or tied to a pole or furniture. Some traditional weavers weave between two poles, similar to the Oseberg loom found in Norway dating from the 9th century, and wrap the weft around the poles. Commercial "tablet weaving looms" adapt this idea, and are convenient because they make it easy to put the work down. Other weavers prefer to use "Inkle" looms, which are a more modern invention, but acts as both loom and warping board for the project.
