craftgrrl | Bookbinding Adhesive Question (Reply)

I'm thinking about trying to make some perfect-bound journals, but it's currently too cold in my area to mail-order PVA bookbinding glue (according to the California Paper Goods web site, if it freezes while being delivered, the glue will be ruined). However, I have an unopened jar of Mod Podge Matte sitting on my shelf (bought for a project that was later abandoned), and I'm wondering if it would hold up to the task? (It would be nice to use it up, for sure). However, I've never used Mod Podge before, and I'm worried that it might be too brittle when dry. I know that bookbinding glues have to have the ability to remain flexible when dry, so that the pages of the book can bend freely. I also know that you can use Elmer's all-purpose glue in a pinch, but I've heard that it's better for the longevity of the book spine if you use PVA meant for bookbinding (Elmer's is a kind of PVA glue, too, is this right?). Any thoughts or advice out there? (Maybe I'll just experiment with Mod Podge first and if it doesn't work I'll buy some Elmer's or wait for spring to order my PVA).

And so that this isn't text only, the little package I sent to my SO for valentine's day (Closeups below the cut). I hand drew the gift tags based on the design of the Oxfam card you see at the bottom left of the image above the cut. I've written a little bit more about the gift and the places whose maps appear on each tag on my wordpress blog, if you're interested.
