This is goatskin inside and out. The belt of course is from down the spine if the bovine.
I always burnish edges of the loops. Just how I was taught. A little hide glue and boiling water makes a nice edging and a rough piece of canvas brings it to a nice burnish.
I think sliding (running) loops on strapping goes way back. A loop on a belt bag from medieval times is nothing more than a running keeper.
A runner keeps things from flopping and is used in saddlery/harness as well.
The scalloping was done with a punch given me by Eric. I will always treasure it.
I didn't make the buckle. It is actually japanned.
I had trouble with my lighting booth colorand the color is more like this closeup.
