a mitered corner is when two sides come together at a 45 degree angle. you can use this technique to create a polished look on many sewing projects like tablecloths, blankets, quilts, and curtains. you can make mitered corners just about any size. this example will have a 1 inch mitered corner. fold the fabric over 1/4 to 1/2 an inch and press it. then fold it over again however wide you want the border to be and iron it. repeat these steps on all the other corners. open the fabric so just the first crease is folded over.
measure 2 times the width of your border from the corner down each side. draw a line connecting the two marks. next, fold the corner in half diagonally with the wrong side facing out. make sure the two marks line up and pin it together. sew down the marked line. backstitch at the beginning and end, and sew all the way to the edges. cut off the excess fabric about 1/4 inch from the seam. turn it right side out, and push the point of the corner out. if you want to add a backing, slide it under the mitered corner.
finally, topstitch around the inner edge. and that's it, an easy mitered corner that you can use on many projects.
