I have to bind a 50 inch tree skirt. Because of it being round I am guessing I am going to have to cut my binding on the bias. I have 1/2 yard of the binding color. Will this be enough fabric to bind the outside edge plus the inside edge of the
tree skirt? I just can't wrap my head around figuring out the yardage when I have to cut on the bias. I was going to do the binding at 2 1/4". Thanks for any help or advice!
