One end of the main piece needs to be cut so that it forms the flap. I made a template and used that to scribe a line which I then cut with the round knife. Before cutting mark the center(this will make it easier to position the hasp) A line for the stitches is marked around 3mm from the edge and all the edges are beveled.The marking of the stitches begins in the center of the gusset as shown in the "gusset" step.

To determine where the lock should be positioned I assembled the bag with paper clamps and marked the leather. This step sounds simple be it actually takes some time. You go back and forth moving the flap up and down to see what works best. Also the length of the main piece was cut to long so this had to be trimmed as well.

To make the hasp fit the flap the tip as to be cut flat. Take off a little at a time so you dont end up taking too much off. Lay the hasp and mark the holes with either a awl or a small round punch.

Before you rivet the hasp in place you should burnish the flap and the top edge.

The hole for the lock is easy to mark if you have the back plate. At this point I had already covered it in leather and did not want to take it out again. Therefore I just measured the lock and made some cutting lines.The hole is easy to cut but the indents for the rivets are a real pain. I used a combination of round punches and a knife to make them.
