I was working on Simplicity 1499 and I didn't like the instructions for the bias tape with mitered corners. I got a lot of experience working on Simplicity 1422, and I realized I'd never talked about the seam binding. So today, I'm sharing my method which I feel is the BEST and EASIEST way to get that great mitered corner.
You can make your seam binding or you can buy prepackaged. For this instance, I'm using prepackaged.BERNINA #1 foot and my BERNINA #5 foot (it's my stitch in the ditch foot).
Keeping your needle in the down position, raise your presser foot and turn your project to 45° angle and stitch down into the point.
