What are endpapers?
These are the pages you see when you first open the cover of a (hardback) book. They join the book block (pages) to the inside of the hard cover. They are often patterned or coloured. Traditionally endpapers were decorated with marbled patterns and other methods of decoration.
Sometimes, bookbinders miss out this stage and use the first and last pages of the sections to connect the book block to the inside of the cover. If you do this, make sure the grain direction of the paper in the sections is running head to tail.

Choose a decent weight of paper for your endpapers, say 150-160gsm and make sure the grain direction of the paper runs head to tail.
Press the fold of the endpaper well and attach to the pages as follows:
