Leatherimages, you're right, they were sewn inside out. As for tunnel stitching, sort of, I think. The stitching's done on an angle so it comes out through the side of the sole. I went to the library and they had a video on how to make these, including instructions on how to make the pattern. These are not that hard to make, but they're by no means a one-size-fits-all moc..
Harvey, the soles on these aren't rawhide, that'd be Apache, and I think they sewed theirs differently. I know what you mean about being slick, though. The vegtan soles about put me on my behind, walking on the carpet. Traction? Not so much. I have been looking at different things to put on the bottom of them, and will probably end up painting them with some sort of rubber.
