Mitred border corners provide a professional looking finish to many quilts, and should be used when they complement the overall design of the quilt. For multiple borders, sew the strips together first, before attaching them to the quilt as one unit.

Step 1. To find the required length of the border strips first measure the width of the border and multiply this by two, add this measurement to  the width of the quilt, now add 2". Cut 2 border strips this length. Now add twice the border width to the length of the quilt and add 2". Cut 2 strips this length for the side borders

eg. width of quilt before border = 65"; width of border to be added = 6"

i.e. 65" + 6" + 6" + 2" = strip 79" long. Cut 2 strips 79" long (width measurement).

Repeat these steps for the length of the quilt.

Step 2. Centre and pin the border strips in place. Begin and end the seam 1/4" from the raw edges, backstitch to secure. Press the seams towards the quilt top.

Step 4. Fold the quilt on the diagonal with right sides together. Align the raw edges of the border strips, and the creases and pin in place. Stitch along the crease line beginning at the point where the  border seams and the quilt all meet.

Step 5. Press the seam open. With the quilt right side up check the accuracy of the mitre by placing the straight edge of your quilting ruler along the edge of your quilt, aligning the 45 degree angle line of your ruler on the seam line. If the corner is flat and square, trim the excess fabric from the borders to a 1/4" seam allowance.

For multiple mitred borders, sew the border strips together first and attach them to the quilt as one unit.
