Thank you I will have to check it out!
As for the strap 1" buckle is 26mm according to watches. I typically make a common size of 75mm/130mm, the 130mm just gets smaller or larger depending on customer. the back depends on the material I am using, if I have a solid piece I will just fold it over and cut down to length, if it is a thin piece I will add a second piece as backing then skive down the tips of the front piece, fold over, glue, then stitch. I can get pics of it later today for you.
