The Piano Hinge binding was created by Hedi Kyle. Directions can be found in a variety of books including: Non-Adhesive Binding: Books Without Paste or Glue by Keith Smith, Cover to Cover, by Shereen LaPlantz and Creating Handmade Books, by Alisa Golden. It is a relatively simple binding wherein the spines of the pages are notched and woven together using sticks, string or even paper. The book can be displayed open in the round or closed with the spine showing off the binding. This versatility makes it a good structure to have in your repertoire.
