I also use at least 2 borders every time. First is a very narrow (maybe 1/4" - 1/2") stop border to frame the blocks and let the eye rest. Then I add a border that is proportional to the size of the quilt. If it's, say, 42" x 42" then I usually end up with a 4" finished border. Then I add a contrasting binding which acts as my third border. I audition the widths/colors by laying the quilt onto the fabric I'm considering.
