Do you mean the binding. Which is the final step in making the quilt. I always plan on 3/4 yd for the binding. Also I have made my borders many different sizes. Sometimes a 3in. one followed by a 1 1/2 in. one then a four inch one. Also I have put flying geese up a third of the border on one side and did the same on the other. Gave it an interesting look. Just use your imagination and go for it.
