STEP 2: GLUE THE EDGES
Mix about a teaspoon of glue with a little bit of water. You want the glue to be smooth enough to paint onto the edges of the book, but not so wet that it will take forever to dry.
This is the step where I learned that a piece of waxed paper between the cover and the pages would be handy…
Fan the book pages a little so that they aren’t tightly packed, then paint the glue mixture onto the edges of the pages. Plop something heavy on top of the book, rinse out your paintbrush and cover the bowl for round 2, then read a book while you wait for the glue to dry.
When the edges of the book are dry, they will no longer be cool to the touch. Repeat step 2 twice more, for a total of three layers of glue. You may need to replace the waxed paper; once it gets soaked through, it tends to stick more.
