I concur with LovingIsabella There are 196 blocks (14x14) in your quilt, and half are solids, so that's 98 solid blocks. You can get 6 blocks in a strip cut 6.5" x WOF. That means you need 98/6 = 17 strips, each 6.5" wide, so that's 110.5" fabric, or 3 yards and 2.5". Allowing for shrinkage and squaring up the fabric, you might get by with 3.25 yards, but I would go for 3.5. And if you add 3/4 yard for binding, you might want to make it at least 4 to 4.25 yards.
