First, I had to make 13 blocks instead of 12. Second, I changed the sashing from 6" to 4" so that there would be less white space, but still plenty of room for fancy quilting.

I like lime green - have I told you that yet? I bet I have. I also like turquoise and teal. So for this quilt, I used the green in place of the gray called for in the pattern, and used different fabrics for the centers and the surroundings for each block. I have a lot of lime green fabrics. Who knew how much, just a lot! I also have a lot of turquoise and teal. Yes, many piles reside in my stash.
So fast forward. In order to do an on-point setting, I had to calculate the size of the setting triangles for the edges. Since I had 12" blocks and 4" sashing, this was an easy calculation = 16". I drafted a pattern on freezer paper that was 16" on each edge. This was placed on the white fabric so that the long edge was on the grain line lined up with the selvage edges. Then I folded this pattern in half, and cut another pattern for the corner triangles. Those were placed on the white fabric so that the long edge was on the diagonal. Paying attention to the grain line is important to make sure the outside edges are on grain when the top is completely sewn.

I always over-cut the setting triangles so that the quilt can be squared up in the end. In order to get the right sized triangle to fit, I marked the 16" from the corners, and made sure this lined up with the edges of the blocks.

The top ended up measuring 60"x 60". Here it is almost done sewing. This picture shows how you sew the rows to get the on-point setting. It's sewn into diagonal rows. Then the rows are sewn together.

I hope you like it so far.
