I use the machine for my charity quilts also, and I really don't think they look all that bad. I sew binding from the back, flip to front and pin-miter the corners...pinning around. Then I use the stitch that looks like a zig zag, except the zigs and zags are little machine stitches. Onto the binding with a zig and off on the quilt with a zag. Have I explained so anyone understands? I can adjust my "ZZ" to the width that looks good, and the little sewing stitches are about lgth 2 1/2 on the dial. Sometimes a 3. You just need to slow down and maneuver the corners to get them right.
