Everyone has already explained the way I handle my machine binding, but I would like to add I choose a bobbin thread the same color as the quilting thread or one that matches the fabric. It will either look the same as the quilting or blend so it isn't noticeable depending on which thread color you use. I also use a longer stitch when sewing the binding. On my machine I use 3.0 -3.50 depending on the look I want. I have on a few occasions used a fancy stitch.
