Hello all, I do some degree of casual work (i.e. occasional holster, pouch, whatever) but I have a project which I need some advice on. The item I'm making/copying has a strap with a set of parallel lines along each edge that appears to have been applied with some sort of embossing wheel. Mind you, they're just like a pinstripe, not a design like barbed wire or chains or anything like that.
What kind of tool or technique do I need to duplicate this effect? I've given thought to rigging a washer into my overstitch wheel but since there's no guide I would have a hard time keeping the line perfectly parallel to the edge of the leather. I'm sure there has to be a specialized tool for this. Thanks,
Jon
