Masgrimes Lining Triangle

Developed by leading American penman and penmanship historian, David Grimes, the Masgrimes Lining Triangle draws inspiration from a number of contemporary and vintage tools like the Ritchie Wei ruler, Soennecken “Rundschrift-Maass,” and Ames Lettering Guide. This modern solution for drawing consistent, evenly-spaced guidelines delivers an intuitive and versatile tool for every pointed pen calligrapher.

  • COMPACT SIZE: Designed for us with A4 sizes and smaller, the Lining Triangle is large enough to offer utility across a range of project sizes but small enough to easily fit into calligraphy travel cases for lining on the go.
  • VERSATILE: Offers ability to product slant lines at both 52° and 55° CONVENIENT: Housed in resealable pouch, perfect for storing in any studio setting or to keep pristine when using on the go!
