This is a reconstruction of an 18th century book of weaving tie ups and profile drafts by Jacob Angstadt. The book was reproduced by Ruth Holryod who holds the copyright. That being said, there is nothing to prevent any weaver from using the many drafts and profiles in the book in their work. There are a limited number of drafts for 8 shafts and fewer than 8 shafts, but with 12 shafts the drafts become more numerous and it continues to expand until the limit of 32 shafts.

Many of the tie ups and draw downs can be found in other 18th century works on Handweaving.net, but the profile drafts are the real meat in this elegant volume. There are two separate volumes that go with this work. Jacob Angstadt: His Diaber Book and Jacob Angstadt: His Weaver's Patron Book.
