A mitered corner is a binding technique for a quilt or other sewing project that creates a 45 degree angle at the corner of the project. The technique creates a sharp and professional look for your quilt. Learning how to miter your corner can elevate a beginning quilt to a more advanced level. If you are intending to enter your quilt into a quilt show, a mitered corner is an absolute necessity. Working with a satin ribbon can be more difficult because the fabric is more slick when it comes to handling.
Measure the circumference of your project.
Obtain a length of ribbon equal to the circumference of your project plus 2 inches. If you cannot find a length of ribbon long enough, you can sew several smaller pieces together to get the length you need.
Fold the ribbon in half lengthwise and press. Be very careful when pressing not to scorch the satin material.
Pin the ribbon to the edge of the blanket, beginning in the middle of a side. You will be laying the binding along the top of the quilt, with the raw edges of the quilt lining up with the open ends of the binding and the folded side of the binding pointing in towards the center of the quilt. You will be sewing through both sides of the satin ribbon as well as the quilt itself.
Stitch through the ribbon and blanket until you reach a corner. Fold the ribbon back on itself to create a 45 degree angle, pinning to hold in place.
Stitch down the next side, back stitching to secure it.
Pin the ribbon down the adjacent side and repeat the process until you have bound the entire quilt.
Secure the edges of the binding with a simple straight stitch when you reach the beginning of the binding.
Turn the quilt over and fold the binding over to the back. This will be the folded side of the satin ribbon.
Pin it into place and hand sew the binding the back, repeating the mitering when you reach each corner.
Satin can be slippery and difficult to work with. Use extra pins to secure the ribbon and shorten the stitch length if you're having trouble keeping the ribbon from moving while you sew.
