Bookbinding and Leather Glue

Posted by request; this is from an old arts and crafts recipe book. I've used it for making cardboard and cloth/paper book projects with the kids, though I haven't tried to repair actual books with it so can't vouch for that. According to the recipe, it is excellent for binding leather to leather and is a flexible glue for paper or gluing cloth to cardboard, etc. This makes about 1/3 cup; you can double it for larger projects.
