Do not use glue.
Seemed like a good idea at the time.
Take it to a specialist that works with leather and have them do it.
If you hand stich it, it's going to look like ass.
If you put it under a sewing machine, it'll look better, but then your liner is going to be all cattywhompus.
Spend a few bucks and get it done right.
I wish I had.
