Mitered corners look great on quilts. Many quilters shy away from sewing them because it seems complicated. Break it down to these 5 simple steps and get the results you want every time.
Step 1: Cut Border StripsIn this example we use a quilt top that measures 11" x 14".
Width or length + cut border width + cut border width + 1"The 1" is a little extra.
Side Border Strips
14" + 3-1/2" + 3-1/2" +1" =22"
Top and bottom Border Strips
11" + 3-1/2" + 3-1/2" + 1" = 19"

Step 2: Mark the CornersI suggest you don't skip this step. On the quilt top, mark each corner where the two seam allowances intersect.
Step 3: Sew All Borders to TopStart with any side, top or bottom. Find the centers of the border strip and the edge you are sewing. Match the centers and pin between the center and the marked corners.
Stitch a 1/4" seam from one marked corner to the other. This will leave the seam open on each side.
Step 4: Press SeamsPress the seam towards the quilt top. Repeat steps 3 and 4 with the remaining quilt sides.
Step 5: Mark and Stitch the MiterIn this step you will fold, mark and stitch the miter in each corner, one at a time.
Stitch along the marked line.
