Probably, just look for grain in fabric, I've not worked with denim before but you might want to allow yourself alittle more than 2 1/8 width Because of the thickness of it. Also 5/16 is more than 1/4. Did you mean 3/16? I think that what the other ladies suggested, 2 1/2 would prob be about right. All the best with it and keep us posted :)
