Are you wanting borders for each block or for the whole quilt?

I put this into my Robert Kaufman app for my i-phone. I put in a 14 X 14 in block to make sure that we had a little "extra". For one block it states you need a 1/4 yard - cut 2 3.5 inch strips.

If doing for the whole quilt, I just need the overall size of the whole quilt. I love this app.
