I have redone many cases and built new ones and I have come to rely on simple Elmer's white glue. However, unlike hide glue, it can't be easily removed. The trick is to use it sparingly so that no glue seeps through the fabric. If it does seep through, there will be a hard spot. Practice first before starting on your case.

I don't know the source of your baise fabric, but I always use premium heavy billiard cloth from a pool table repair source.
