Jinny Beyer uses border fabrics a lot in her patterns and she also likes to miter her corners. She has a video to show how to do it. I was making one of her patterns, the Crystal Star and ordered her border fabric to go with it. Watched her video before I started chopping away. Worked perfectly going by her directions. I'm the sort that needs to see it done and not just read how to do it so the video helped me.
