i connected the three O-rings together and secured them with an single nail. i am still unsure but i think next time i better stitch the strap together for more strength and give them a nail. also i think i going to use a thinner version of these O-rings. these ones are kind of really heavy.

still i see some errors in the stitch, working on that. i need to get used to the machines and how they respond i think that in the end of this month or start next month i get it corrected by making enough collars.

i am over all pleased with these collars. besides the stitching is not 100% straight and i make some cutting errors they come out nicely.
