If I were to make a king size quilt, I would buy 9 yards for the obw center.
Then a solid color from the fabric for an inner border.
Then I like to make an outer border of the original fabric so you can see where it came from. For this you would have to calculate how wide the last border would be and buy that much additional fabric.
Bind with the solid.
This is how I have done them and I like the way it looks, but this is your quilt. Just enjoy the fun of laying out all the hexagon blocks to create your center. Ann )
