The tools & supplies needed for this project are pretty simple. You will need some 1″ webbing, a pair of scissors, a measuring tape, a D-ring, three sliders and a sewing machine.
If you can’t find the sliders, metal O-rings or D-rings will do just fine. But you will need a plastic slidelock for the adjustable part of the collar.
Some sources that I use for hardware & supplies are

but frankly, it's easier to get the webbing at your local fabric store & more of the fabric stores also sell the hardware.
