coin case

I need a coin case for me.

 I had used same form one. I don't like this form as maker, because it isn't so economical.

 I used cutting board to make it.

 This is wrong. The tool is used for marking on the surface.

 The thickness of the leather is enough thick for this coin case.

I tried making some variations.

 Above one is painted. My painting skill looks like kindergarten level.
