I take a 2oz veg tan leather strip that I purchase from Hidecrafter's in Fort Worth, Tx. I coat both the belt and liner straps with contact cement. I then allow them to dry before I join the together. How do I know if the glue is 'dry?' When I apply the glue it has a 'wet' look. When the shining or 'wet' is gone I know it is dry. If you want to add strenght, apply a second coat of glue and allow it to dry before joining your pieces. The second process works well when you have to wet your leather completely for moulding.
