That binder who told me to stop using wheat paste for everything was right
I used to be one of those people who swore by wheat paste for every single book project. Leather, cloth, paper joints, you name it, I was mixing up a batch. Then this older binder at a workshop in Portland last April pulled me aside and told me I was ruining my spines by using something so stiff on flexible materials. I got defensive at first, but she showed me how my last three rebinds had cracks forming right along the hinge because the paste wasn't giving at all. So I switched to a PVA mix for the spine area and kept wheat paste just for paper-to-paper stuff. It hurt my pride a little, but my books are actually lasting way longer now. Has anyone else had to give up a favorite adhesive for something more flexible?
