Seersucker is a type of cloth with wrinkled stripes. According to Wikipedia, "The word came into English from Persian, and originates from the words "Sheer" and "Shakar", literally meaning "milk and sugar", probably from the resemblance of its smooth and rough stripes to the smooth texture of milk and the bumpy texture of sugar." Most people think of it as the material used in summer weight clothing for men's suits or garden party dresses. I don't know of many handweavers attempting it because to do it for longer lengths of cloth you should put the stripes on a second beam. For looms that have a conventional friction brake everytime the weaver needs to advance the warp each warp beam has to be released, the woven cloth rolled to the cloth beam, and the tension restablished on both beams. With my AVL looms each beam can be individually tensioned and once the tension is set at the beginning of the warp no further adjustment is necessary. I know this works because I have done it on my smaller AVL but for that project I did not want to have one beam tensioned higher than the other.
My current project is on the big lom, 42" wide, the sectional beam is loaded with a combo of 10/2s tencel and cotton, end on end. The plain beam has 12/2s cotton. You wouldn't think the yarn size was significant but the 12/2s cotton is much finer. The loom is threaded in straight draw, shafts 1-12 are for the cotton/tencel and shafts 13-16 are for the 12/2s. My sett is 32 epi. My loom looks like a disorganized mess because I have the threading cross from each beam hanging on their individual lease sticks. Cross-checking my threading is super important because if I make a threading error I have to fix the problem for both beams.
