To complete the bookbinding covering material we stock I add an interesting textured material, coated paper, also used for endpapers plus fake and real leather.
The coated paper is generally used only on small books, as infill when making quarter leather bindings but is great for endpapers when larger sizes are required. It is inexpensive and a very wide material.
The fake leathers are a PVC material but great for when the leather look is required and real skins are too expenssive for the client.
