I always double the binding for projects that will get a lot of use.. that's the first thing that wears out. And I'm basically a hand stitcher.. so I sew the raw edges side by machine to the back, flip it forward, then hand stitch the binding to the front. I use bias binding on curved edges and flat "on the grain" binding on simple square edges.

I cut my own binding - it's like cutting strips for the quilt - at 2-1/2", fold in half and press, sew it onto the quilt at either 1/4" or 3/8", fold it over onto the back and baste it with washable glue. I happen to use Roxanne's with that very fine tip. As I fold it over and glue it I press it and it dries the glue right away. No pins to get stuck with as you sew your binding whether by machine or by hand. I do most of mine by hand just because I like the finished look but that is personal preference.
