The drawers need a way to be pulled open. For this project I added leather handles to the drawers. I did not use pre-made metal handles because they aren't flexible (may interfere with the case closing) and they are a hard surface that a glass object could break on if they hit just right.
I used a similar technique to attach the handles as I did for the hooks and loops. I pre-punched holes in the leather to create stitching points, transferred the marks to the wood, and drilled holes. I then used a needle and thread to sew the handle to the drawer fronts.
One of my drawers is pretty narrow front to back. I used a curved needle to sew the handle to the drawer front.
