Weaving sett calculator

Thanks to Sharon Alderman for giving us permission to use the sett formula, tips and thoughts from her book, Mastering Weave Structures: Turning Ideas Into Great Cloth. Sharon acknowledges that this formula predates the publication of her book by several decades.  However, Sharon has revised the process to include consideration of mixed warps, upholstery fabric, slippery yarns, and other special warps, thus giving the weaver a better understanding of the formula and how it can be used.

Reed substitution, knitting needles and crochet hooks.

Aspects of this spreadsheet first appeared as a warp and weft calculator in an article by Ruth Blau in Weaver's #26, Winter 1994. Marg Coe subsequently expanded the spreadsheet to include many other calculations of interest to weavers, dyers, etc. The spreadsheet has been incorporated into the functionality of Weavolution with the permission of the two authors. For information on purchasing the actual Excel (tm) spreadsheet, please contact Marg Coe at
