Since it is a pieced boarder, it only comes in certain sizes, I have it 30x40, I have to figure out how to make it 10 inches to mach both side for it to or add pieces to make it big enough to get it in. I might have to rework some math here, i am sure that everyone is smelling smoke at this point.
I usually fill in the points, on this one due to time, I am cutting them off, the way I put it together I would have a Y seam to do it. If you change the direction of your seams it works in really nicely without Y's
