I am thinking about trying a different approach ti saddle stitching. I have used an over-stitcher to space my stitches and then either stabbed the holes with my awl and stitching or drilling the holes and then stitching.
I am thinking of using a pricking iron to make the holes and using the awl to open them while stitching.
I saw a complete set of pricking irons on ebay that are made in China. Has anyone had any experience with them?
