Blue leather greyhound collar

I always enjoy creating these collars for greyhounds: they are wide in the middle and allow you to give free rein to your creativity! This one was originally a fairly thick vegetable-tanned natural leather, which I embossed to create the flowers, then dyed and protected. Then I lined it and hand-stitched it with saddle stitch and waxed linen thread. And I fitted the buckle (nickel-free!). Width for Whippet 5 cm, for big greyhound 6 cm (at the widest). For the length, please tell me above the breed of your companion and its neck size!
