Looks nice, Billy. I'm also a builder Are you hand stitching, or using a machine? I'd imagine a machine, because when you saddle stitch by hand, the extra row of stitching isn't necessary. My only nitpick, and take it for what it's worth, but on your throat reinforcement, you may want to round those corners a little more next time. Over time, those will begin to fray. Great job, and keep on building. Your molding and boning look nice. I rarely touch revolvers because they're such a pain to mold.
EDIT: Upon further inspection, it looks like the corners on the reinforcement are rounded, it's just the stitching that comes to sharp point. Disregard.
