Would it be possible to post a closeup of the border ? I'm trying a help a friend figure it out. She has all her 4 patches made and will sash and cornerstone them. We know you put your blocks on point on the border. What we can't figure out is the cornerstones appear to be staggered. Did you sash and cornerstone just 3 sides, then set the blocks on point ? Thanks so much, this quilt is beautiful.
