I'm still at it with mine, of the four I have added sash to three are 11" across, and one is about 11 1/8. All of them should be 11 1/4" One I had to make a small seam allowance if I hadn't the seam would have cut off one of my points, which it did and I had to take out and do again. It's a good thing I'm not a quitter. I would have moved on to something else, but I have too much time in this to quit now. I guess the anxiety is that you think you are being so accurate and boom, you measure and give a big sigh of disgust and then do it again. The joy of quilting. I must love it because no one makes me do it but me. Hang in ther FanoFabric and I will to.
HAPPY QUILTING EVERYONE
