What are the dimensions of the piece of fabric you have available for the binding?


The theoretical formula for figuring out if one has "enough" fabric:

Area of binding (length x width) needs to be less than area of fabric available (length x width).


Area of binding = width of binding x length of binding : 2.5 x 272 = 680 square inches

Area of fabric available = width of fabric x length of fabric : 31 inches x ______________?

680 divided by 31 = 21.94 inches. (Which would not be quite enough - in my experience.)


Remember to allow for "waste" - what is too small for the intended use and fabric "disappearance" - I am not sure where it goes, but if I am trying to get ten 3-inch cuts out of a 30 inch piece of fabric - I will only be able to get nine cuts.
