Creating a mitered corner when binding a quilt adds a professional touch and prevents bulk at the corners. This technique is particularly useful for quilts with borders or those made with thick fabrics. Here's a step-by-step guide to help you achieve perfect mitered corners every time.

Before we dive into the process, ensure you have the right tools and materials. You'll need a rotary cutter, quilting ruler, walking foot for your sewing machine, binding strips (cut on the bias for better flexibility), and a sharp pencil.

Preparing Your Quilt and Binding Strips
Begin by measuring the length of one side of your quilt. This will be the length of your binding strip. For a 45-degree miter, you'll need a binding strip that's twice the width of your quilt plus 1/2 inch for overlap and seam allowance.

Cut your binding strips on the bias. Bias binding stretches better than straight grain binding, which is crucial for creating smooth mitered corners.
Marking the Miter Points

With your quilt and binding strips prepared, it's time to mark the miter points. Start by folding one end of your binding strip in half lengthwise, wrong sides together. Place this folded edge along one side of your quilt, aligning the raw edges. Mark the corner of your quilt with a pencil.
Next, open up the binding strip and mark a line from the corner mark to the opposite edge of the binding strip. This line will help you sew the miter accurately.
Sewing the Miter

With your marks in place, it's time to sew the miter. Fold the binding strip back on itself along the line you've drawn, right sides together. Sew along this fold using a 1/4 inch seam allowance, starting and stopping at the corner mark.
Once sewn, press the seam open. Then, fold the binding strip back over the edge of your quilt, right sides together. Sew along the raw edge of the binding strip, using a 1/4 inch seam allowance. Stop sewing at the corner mark.
Attaching the Binding to the Quilt

Now that you've sewn the miter, it's time to attach the binding to the rest of the quilt. Fold the binding strip back over the edge of your quilt, enclosing the raw edge. Sew along the folded edge, using a 1/4 inch seam allowance.
Repeat this process for all four sides of your quilt, creating mitered corners at each intersection.




















Finishing the Binding
Once all four sides are attached, it's time to finish the binding. Fold the binding strip to the back of the quilt, enclosing the raw edge. Sew along the folded edge, using a 1/4 inch seam allowance. Be sure to overlap the ends of the binding strip to create a neat finish.
For a more polished look, you can hand-stitch the binding to the back of the quilt using a ladder stitch or blind stitch. This will ensure that the binding is secure and won't fray over time.
Congratulations! You've now successfully created mitered corners when binding a quilt. This technique not only looks professional but also prevents bulk at the corners, making your quilt more comfortable to use and display. Happy quilting!
