Step 17: Gluesurface and Lining Together.
You should fold the surface and glue the lining, here is a very important skill "Bending glue", that means a short lining than surface will make the wallet bend naturally, I designed the lining shorter than surface, so you should glue and bend gradually, until the edge of lining and surface align neatly, then you get a nature bending wallet.
Step 18: Punch Stitching Lines From Surface to Lining.
After "blending glue", when you unfold the wallet, you will see it is not flat. Punch chisel from surface to lining.
