A one-page question-and-answer column by Mary M. Atwater explaining what the lease is in weaving: the cross in the warp that makes the tabby shed, and especially the cross made on the warping board or drum when making a warp chain. She explains why a lease matters for chained warps, why it is unnecessary in sectional warping, and argues that lease sticks at the back of the loom are not needed during weaving.
