Fabric wrapped around a cord is called piping; leather wrapped around a cord is called beading. I’ve put handmade beading at the tops of these boots. I like to use a delicate little cord and finely skive the leather, because if the beading is too fat it looks like a big ol’ worm crawling on the top of the boots.
I'm a custom cowboy boot maker. I own a business, Sorrell Custom Boots, and I create bespoke cowboy boots using vintage machinery and hand tools. I also own www.sorrellnotionsandfindings.com, a company that specializes in tools, supplies, and leather for the boot and shoe making trade.
