Don't you love it when a plan comes together! I used a different brown and rust fabric in the 1/2 inch border. The brown that I chose for the blocks was only a 10 inch square, and the rust fabric in the points and setting square/triangles was a fat quarter. I need the rest of that fabric for the points in the border piecing.... It is astonishing how much fabric this tiny quilt has used, but there is lots of trimming, no matter how careful I am.
I'm proud of my mitered corners. The borders were sewn together first, then treated a one. I have tried many methods to miter the corners, but finally decided to use Sharon Schamber's method. You use "Elmer's School Glue" with a tiny applicator tip and a hot, dry iron to glue-pin the miter. Then you open up the seam and stitch on the pressed line, pull the glue apart, trim the seam allowance and press the corner seam open. I have had great success with this method.
