Now that the riggins are dry, they are riveted and sewn. Notice in the second photo how the edges are tapered and notice on the top riggin how the stitches are not only recessed in the stitch groove but they are also pounded over to help protect against wear from the stirrup leathers(the bottom rig was pounded after the photo was taken)

then I edge the riggins and slick the edges, you can see in the photo the tools used to edge and slick.
