The Triangle Book
Instructor Karen Hanmer

Virtual Workshop
Saturday May 8, 2021
10 AM to 1 PM Eastern Daylight Time
From wherever you are, via Zoom

This artists’ book structure functions on numerous levels: as a codex held in the hand and read page by page in sequence, as a sculpture, and as a delightful object to play with. It can be made in a home studio with minimal specialized equipment. Instruction will focus on both craft and content. Students will have the opportunity to examine a variety of finished pieces and models. Importance of creating and refining prototypes will be stressed. Your finished book, plus detailed instructions, will be a valuable reference for future work.


Advance registration is required for all JCBA workshops. For more details or to register, please email JCBA Director John Cutrone ( John will send you an email explaining how to pay your tuition online. It's a simple process.


This workshop has a set tuition fee of $100.

Required Tools:

• Tablet of computer with Internet connection
• Letter-sized waste paper
• Teflon or bone folder
• Small cutting mat
• Small scissors
• Ruler
• Metal straightedge that can be cut against (this can be the ruler)
• X-Acto/scalpel/Olfa knife and extra blades
• 30/60/90 triangle. (Note: these angles must be accurate. The neatness of this structure depends on the paper triangles being cut as accurately as possible.)
• Small brush for PVA
• 3/4” or 1” blue masking tape or similar easily removable tape for hinging while determining pattern


• Paint trim pad (this is neater than a brush and the ideal tool for the triangle book)
• Black broad chisel point calligraphy marker
• Covered brick or equivalent weight
• Pressboards
• Whatever tools not on this list you always find useful

Required Materials:

The workshop model has a folded page size of 5" tall and roughly 5.75" on each side. Of course, future books you make using this structure can be any size you wish. The dimensions given for some pieces are rough cut only. The workshop will provide information for cutting each piece to size in relation to other parts of the binding.

If you are making an important book that has a very large page size or is significantly thicker than the workshop book or a book that is significantly smaller in scale, make a model first to determine if the structure is appropriate, and what materials need to be scaled up or down.

• Stonehenge or similar weight paper (250 gsm/90#): 1 sheet cut into 6 strips @ 5” will make 36 triangles. If you are using paper that has already been printed/decorated in some way, you must be prepared to be very flexible about where the cuts are made when it is cut down into triangles.
• Thin book cloth that is not paper-backed like Dover or Kennett from Talas: 17 pieces @ 3/4 x 6”.
• A spacer: 20 pt card, or comparable thickness styrene to be cut into a spacer. Begin with a piece 6” square.


Karen Hanmer's artist-made books are physical manifestations of personal essays intertwining history, culture, politics, science, and technology. She utilizes both traditional and contemporary book structures, and the work is often playful in content or format. Hanmer's work is included in collections ranging from The British Library and the Library of Congress to Stanford University and Graceland, and of course the Jaffe Collection. She offers workshops and private instruction focusing on a solid foundation in traditional binding skills.
