Elena, and other friends, I have heard that color-coded working diagrams were developed in Belgium in the 1930s. Before that a numbering system was used by some authors, with lengthy explanations for each number corresponding to the hole in the pricking.
Frieda Lipperheide, 1898, Das Spitzenkloppeln https://www2.cs.arizona.edu/patterns/weaving/books/lf_lace_1.pdf developed a fascinating grid system of explaining the stitches. Even if you cannot interpret the Old German Gothic text and writing, the illustrations are still fascinating. See page 3 of the book (not the pdf) for the formula, and then scroll further to see it used. Ms. Lipperheide also uses the tiny numbers by each hole, as was also used by other authors in the late 1800s and early 1900s, such as Sara Rasmussen in 1884, and the Torchon Company in the early 1900s. You will find that the Torchon Lace Company copied most of their material from Sara Rasmussens book Kloppelbuch. https://www2.cs.arizona.edu/patterns/weaving/books/rs_lace.pdf The Torchon Lace Company https://www2.cs.arizona.edu/patterns/weaving/monographs/tor_v1_1.pdf You can read more about the Torchon Company in my blog written for the Smithsonian http://americanhistory.si.edu/blog/torchon-lace-company-fine-line-between-entrepreneurship-and-fraud I am not using the umlaut and apostrophe on purpose to avoid the strange symbols that show up in the Arachne posts. -Karen in sunny Washington DC at the moment - To unsubscribe send email to majord...@arachne.com containing the line: unsubscribe lace y...@address.here.
