This is one of my "all out" collars! If you're a person that needs the best and likes your dog to look better than the rest, this will do the trick.
Black on Black Flat Martingale Collar (15 3/4")
Tooled black "English" bridle leather sighthound collar with black lacing, Southwest bezel conchos and blue Swarovski crystals; Hand stitched pull tab; 2" wide tapering to 7/8"; 1" Stainless steel O-rings; 15 3/4" inner circumference
I hand sew with a traditional harness stitch method using needles, thread, and a diamond awl.
Because the flat martingale collar needs to slip over your dog's head, you need to measure the largest point BEFORE it slips onto and over the ears. Using a flexible tape measure is helpful. The measurement around the head will be the inner circumference or inner measurement of the collar. Be careful to avoid fingers under the measuring tape. Remember that it is easier to slide a collar over the head and onto the neck than to pull it off.
