2" x 6" cut to 4.5" wide. I wouldn't go wider unless you are going to make a smaller one for fox. I stenciled a coyote board onto it and cut out the pattern. Cut edges at 45 degrees with a skill saw and then belt sanded to round it out. Cheap and easy to make. Getting a little thin where the knife comes off the pelt at the bottom and I'll probably have to make a new one sometime this season.
Not fancy but it works just fine and all that I need.
