Now I knew the hook and eyes were in the right place ( I could have set them back from the edge a little more), I had to go back reinforce them.  This is quite time consuming and took a fair while.

Stab stitching

To help reduce the gap between the opening side, I also stab stitched through to the other side. Ideally these should not show, or be quite small.

I really wanted to make sure they were secure, so made mine a little wider and put the needle through the fastening hoops 2 or 3 times. I only did this on the hook side as the metal boning would have been in the way on the other side. To even it up, I could have made faux stab stitches on the other front side panel.
