Creating a self-binding quilt with mitered corners can add a touch of elegance and professionalism to your project. Mitered corners, where the edges of the fabric are cut at a 45-degree angle and sewn together, create a seamless, continuous pattern around the edges of your quilt. Here's a step-by-step guide to help you master this technique.

Before you start, ensure you have the right tools and materials. You'll need a rotary cutter, a self-healing mat, a quilting ruler, a sewing machine with a walking foot, and of course, your chosen fabric. Let's dive into the process.

Preparing Your Fabric
Mitered corners require precise cutting. Start by measuring and cutting your fabric into the desired size. For a self-binding quilt, you'll typically want your binding strips to be 2.5 inches wide. Remember to account for the width of your seam allowance when measuring.

Once you've cut your fabric, use a quilting ruler and rotary cutter to cut 45-degree angles into the corners of your quilt top. This will create the mitered edges that you'll sew together.
Sewing the Mitered Corners

Begin by laying out your quilt top with the right sides facing up. Take one of the mitered corners and fold it so the 45-degree angle is pointing towards the center of the quilt. Pin this in place.
Now, take the adjacent side of the quilt and fold it over the mitered corner, right sides facing. The edges of the fabric should align perfectly. Pin this in place as well. You should now have a corner of your quilt that looks like a neat, 90-degree angle.
Sewing the First Seam

Using a walking foot on your sewing machine, sew along the edge of the fabric, starting and ending about 1/4 inch from the corner. This will create a seam that holds the mitered corner in place. Remember to backstitch at the beginning and end to reinforce the seam.
Once you've sewn the first seam, press the seam allowance open to flatten it. This will make it easier to sew the next seam and ensure a neat, professional finish.
Sewing the Second Seam

Now, fold the fabric back so the right sides are facing out. You should see a neat, 45-degree angle at the corner. Pin this in place.
Sew along the edge of the fabric again, starting and ending about 1/4 inch from the corner. This time, you'll be sewing through all the layers of the mitered corner. Again, remember to backstitch at the beginning and end.




















Attaching the Binding
With all your mitered corners sewn, it's time to attach the binding. Cut your binding strips into lengths that will fit around the edges of your quilt, plus an extra 2 inches for overlap.
Starting in the middle of one of the sides, sew the binding to the quilt, leaving a 1/4 inch seam allowance. When you reach a mitered corner, fold the binding up and around the corner, then continue sewing. This will create a neat, mitered corner on your binding as well.
Finishing the Binding
Once you've sewn all the binding to the front of the quilt, fold it over to the back and press. Then, fold it over again, enclosing the raw edge of the binding and the seam allowance. Pin this in place.
Using a slip stitch or a blind hem stitch, sew the binding to the back of the quilt, catching only the binding in your stitches. This will secure the binding in place and create a neat, finished edge on your quilt.
Congratulations! You've now successfully created a self-binding quilt with mitered corners. This technique adds a beautiful, professional touch to any quilt project. Happy quilting!
