I use 2-1/2 inch strips, folded in half, ironed, and use a 1/4" foot to attach the binding strips to the "back" of the quilt. I then turn the strips over, press once again, lightly on the front before stitching. The fold of the binding should be placed very slightly over the 1/4" inch seam line and stitched. I like using a short/narrow zig-zag stitch which catches both the front and the back edges. You can also use a straight stitch or a decorative stitch. Takes a little practice, but the main thing to remember is the placement of the fold of the binding on the stitch line.
