The way I was taught...start in the middle of your top/bottom/side edge leaving a 4-6 in. tail. Sew binding 1/4 in. from edge of quilt to within 1/4 in. of corner. Stop sewing. Flip binding 90 deg. toward the side you have just completed making a 45 degree crease. Begin sewing again 1/4 in. from outside edge. Follow for each corner. When you get to within 4-6 inches from where you started, trim your tails to overlap your binding 2-3 inches. Insert beginning tail of binding to ending tail folding over raw edges and make sure it is 'tight' and flat. Sew to complete. Makes for nice mitered corners every time. Hope this helps.
