yeah! nice mocs!
good tight stitching is key, and looks like you hid em well.
i make the one piece 1700-1800s Ohio era (Wyandot) try not to let any stitches show.
though i do use artificial sinew. the long pieces of "a. sinew" sure help for pulling it up tight.
i won't hog your thread here, i'll post a recent pair on a separate thread.
