Ada Explained: Algebraic Expressions in Handwoven Textiles

104 Sunday AM

Learn about Ada Dietz and her 1952 monograph Algebraic Expressions in Handwoven Textiles. Designed for weavers who are not mathematically gifted, attendees will examine how Dietz’s method can be applied to any weave structure. This seminar will explain her unique naming convention and display samples woven in 2022 by Cross Country Weavers. Attendees will be encouraged (and guided) in designing their own patterns using Ada’s methods with the time remaining. No calculators are needed, and proficiency in algebra is not required.

If attendees would like a hard copy of the Dietz monograph, it can be purchased directly from the publisher, Little Loomhouse ( Free copies may be found on the Internet, but purchasing from the non-profit Little Loomhouse ensures an attendee is receiving a complete publication assembled as the author intended.

Materials fee:  None

Supplies:  Optional.

If attendees want to play with the concepts presented, please bring these supplies:

  • Graph paper/pencil/eraser; or
  • Device with weaving software enabled. (Attendees should be familiar with their own weaving software as this session will not include a weaving-software tutorial.)
