Handmade Ink blue Horween Cavalier leather dog collar with glow in the stitching

Handmade Ink blue Horween Cavalier leather dog collar with glow in the dark stitching. Someone commissioned me to make them this custom dog collar but they backed out. About the collar... The collar width is 1" and the holes requested for sizing are made at 11" - 16". I feel the 11" and 12" holes would be to small of a fit for the collar size and would have to much excess belt so it would be a better fit for 13"-16". The leather is Horween Cavalier Leather in ink blue. The stitching holes were hand punched with 5mm diamond tipped chisels and then saddle stitched with glow in the dark string from tandy leather. The hardware(buckle and d ring) is 1" nickel plated solid brass from buckleguy. I used Chicago screws and so the hardware could be changed if wanted. I would suggest dark haired animals as real leather can bleed!
