It is in the sale patterns kittenquilts... I will say this. I changed it up a little to make it the size I needed. The center is the pretty much the same though.
I changed the construction up too. They say to cut the square into a rectangle and then sew the seams. I marked down the center of the squares and then sewed on either side of the line a scant quarter inch and then cut it apart. A little easier to handle the bias that way.
