Hidden Cloth Jointed Endpaper

I really enjoy old book related newsletters and journals.  They are full of useful tips and provide historical context for the current state of bookbinding, and many are available in electronic form.  To this end I’ve started binding up sets of these, and because I intend to consult them regularly have decided to focus on the robustness of the endpaper.  The inner hinge is often the first point of failure of a case bound book and this is often addressed by reinforcing the hinge in the endpaper by guarding it with cloth or leather.  For the QBG newsletters I used the hidden cloth jointed endpaper which is illustrated by Johnson on page 59 (example 6).

Materials:

Each endpaper will require the following.

  • 1 coloured paper, which when folded is larger than the text block, for the board paper and first flyleaf.
  • 1 plain paper, which when folded is larger than the text block, for the second flyleaf and waste paper.
  • 1 strip of cloth that will take adhesive on both sides.  I have made my own jaconette by starching cotton and calico with Silver Star Starch, or any other light weight book cloth without a plastic coating on one side.   30mm wide works for most books.

Method:

  • Fold the coloured paper.  Expose a 5mm strip along the spine fold and apply 50/50 paste PVA mix.
  • Pitch the strip of cloth to the glue line so that 5mm a cloth attached and the remaining 25mm overhangs the spine.  Firmly rub down under rubbing paper.
  • Fold the 25mm strip around the folded paper.
  • Exposed a 6mm strip along the spine (the cloth plus 1mm of exposed paper) and apply 50/50 paste PVA mix.
  • Pitch the plain paper fold to fold to the coloured paper, covering the cloth strip.  Firmly rub down under rubbing paper.
  • Fold the outermost plain paper around the coloured paper to become the waste sheet.
