Start in the middle of the side and leave a 12" piece hanging. sew around to the corner, make a 45 degree fold back on itself and then fold it back on itself with the fold even with the edge, sew thru the fold and on down to the next corner. Repeat all around. When you get to the end leave another 12 inches and cut the extra off. Fold one corner of the edge at another 45 degree and press, now put the other edge into the fold and trim so there is just a little under the fold. and sew thru it. now just turn to the back and hand stitch. Be sure you get a mitered corner and I sew that down so I get a nice sharp corner. I cut my binding at 2 1/2 " and sew it on with the
1/4 ". Jan
