Been said before, but I stitch to back first, turn to front and top stitch close to edge. I use the color thread that best matches the backing for the bobbin thread. The key to getting all of this really, really even is to trim the quilt edges accurately (very even), and make sure the binding tape is cut and pressed very accurately, the rest is just following the edges with your chosen seam allowance. Top stitching on the top gives a nice finish on the quilt top whichis the most seen of course.:D
