Thank you so much for this. I do struggle with mitered corners. So I hope you don't mind I copied your directions and pictures and I hung it up in my sewing room. These directions will come in really handy for my next quilt.

Another quilter has queried, what happens when you leave those couple of stitches at the corner of the miter when sewing it onto your quilt - you need to backstitch or tie off your threads, and the long arm quilting, should hold your quilt from coming undone. Just to ensure you will not have a problem with the corner coming undone, you can stitch (using your sewing machine - like the stitch you use to attach buttons) and at the very corner on the wrong side of your border.....another couple of pics - there is a button stitch on this pic 6 and 7 shows no puckers, except I did not have enough room on my sample and sewed over the points of the star....[ATTACH=CONFIG]590674[/ATTACH][ATTACH=CONFIG]590675[/ATTACH]

Okay, I get that you sew the corner of the border together first and then stitch. But what I am not clear about is whether you stitch one corner at a time or do you stitch them all four, thus creating a completed "frame" that you then attach to the quilt top? Thanks, in advance, for this clarification.

Jennifer from Fat Quarter shop has an excellent tutorial on Youtube. I find mitered corners hard as well.
Thanks for this post, d rickman. I have trouble with reading directions for this but it will help many others.

Thanks for the pictures and explanations. I will use this as a reference in the future.
