Hi everyone! I’d love to make this style of bag, but I can’t find a single tutorial showing how to make the wrapped/corded edging that goes all around the bag.
I already have the hexagon-shaped leather panels, but I’m completely stuck on how to create the border and attach/make the handles. I’ve searched YouTube and Google with terms like wrapped edge, corded edge, fabric tubing, and webbing, but I haven’t found anything similar.
Does anyone know what this technique is called or have a tutorial (YouTube or otherwise) they could recommend? Any help would be greatly appreciated!
