Preparing Your Fabric

Preparing your fabric correctly is crucial for successful mitered corners.

First, determine the width of your border. For this example, let's say it's 2.5 inches. Cut your border fabric into strips that are 2.5 inches wide and the length of your quilt plus 2 inches (one inch for each corner).

Sewing the First Side

Start by sewing one side of your border to your quilt. Press the seam allowance towards the border.

To create the mitered corner, you'll need to trim the seam allowance at a 45-degree angle. Here's how:

  1. Fold the seam allowance back on itself, creating a crease at a 45-degree angle.
  2. Using your quilting ruler and rotary cutter, trim the seam allowance along this crease.

Sewing the Second Side

Now, it's time to sew the second side of your border. Before you do, make sure the raw edges of the first side and the second side are aligned.

Sew the second side to the quilt, again pressing the seam allowance towards the border. Trim the seam allowance at a 45-degree angle as you did before.

To do this, lay the quilt flat with the right sides of the border facing up. Align the trimmed edges of the border at the corner of the quilt. You should see a neat, 45-degree angle where the two trimmed edges meet.

Sewing the Corner

Sew along the trimmed edge, starting and stopping about 1/4 inch from the corner. This will create a neat, finished corner.

Press the seam allowance open. You may want to use a hammer or a bone folder to ensure a sharp point at the corner.

Finishing the Corner

Fold the border back over the corner, enclosing the raw edges. Press the border in place.

Now, topstitch along the edge of the border, about 1/8 inch from the edge. This will secure the mitered corner in place and finish the edge of your border.

Congratulations! You've just sewn a mitered corner. With a bit more practice, you'll be able to create beautiful, professional-looking borders on all your quilts. Happy quilting!
