Thank you for the comments and compliments. Tree Reaper does know what he is talking about and I think I will make some adjustments, perhaps a much longer spacing in the stitch that is perpindicular so it still has that finish look with less damage to the strength. These collars are mostly for show off, have not sold this design to anybody using this collar for hunting, tracking or pulling dogs such as Pit Bulls, not even sure leather would be the right material for such things, see more seat belt material for those.
Each time you make something you learn something new it seems when working on individual projects vs. mass production stuff. That is what makes this Forum work so well and fun.
