Large Size is made a little differently then the ones you see, these ones have a Hook and Loop Fastener straps sewn onto the Bow Tie. Made with any of the cotton fabric I have and matched with ribbon for the center.Will fit on 1" wide and 3/4" wide collars - 5" long x 3" wide 
 
Small/Medium Size is made the same way as large, except it has elastic strap on the back instead of velcro  as its too wide. They fit 1/2" and 3/4" wide Collars -  3" long X 3" wide
