Like this one?

I bought some leather remnant at a Tandy leather as well as the rabbit fur.
Cut a piece of leather that acts as the back and the flap (one piece) and sew on a loop on the back (2" x 2 1/2")for the belt (towards the top portion of the body but well underneath the flap portion)and put a snap on the flap.
Cut the fur and top piece to shape, (I glued them together before sewing but not really needed, just makes it easier) sew down a strip to hide the edge at the top, add the corresponding snap to the front.
Take a roughly 2 1/2" to 3" wide strip of thinner leather, the length of the remaining edge and sew it down (face to fur) then flip it out and sew down the other edge to the back/flap piece.

Done.
