Begin on the middle of one of the sides of your quilt, pull the binding from the back and wrap it around to the front.
As you near the corner flip the binding up like this.
Keeping your stylus in place, fold the corner of binding back up over the corner of the quilt. You will see it form a beautiful mitered corner.
Please let me know if you need more instruction on anything, I will be happy to explain!
Try this on your next quilt, and let me know how it goes!
