Shed (weaving) - Poor Shed

Poor Shed

There are many things that can cause the warp threads not to separate cleanly, and thus produce a poor shed. A slack warp, threads set too closely in the reed, or increase of friction on the first foot or so of the warp where the threads were handled all cause poor sheds. Fuzzy yarns like mohair can also cause a poor shed. To get a better shed the weaver can lift the harnesses while the reed is against the fabric, or raise only one harness at a time. By weaving in a different manner sometimes a good shed can be created. The weaver can also insert a stick into the shed to clear it, and make way for the shuttle. This option is time-consuming though.
