Robert has given you some good advice. That said plain ol' Elmers white glue has the same attributes as animal glue without the hassels; and is cheap and readily available. I've used it on all the cases I've relined and even stripping a case after the glue dries is no problem(don't ask why I know this; just make sure you have enough fabric on hand), it acts just like the original animal glues used in english trunk cases; mist with water and it softens right up. It works for case labels as well. If you do have a bit glue that seeps through the fabric you can easily clean it up. Wait till the glue dries and use a spray bottle set to mist, spray the spot, brush it up with a toothe brush, dab with a cloth or vaccuum the area, and watch the glue dissapear.I use plastic spackel knifes and plumbers flux brushes to spread the glue and another knife to press the fabric. Good luck.
