I use 2 1/4" inch strips for my binding. Fold in half. Sew with a 1/4" seam. Hand sew to the back.
I prefer double binding because as the quilt wears (and the edges seem to wear quicker) there is double the protection on the edges. You have to get a sizable hole on the outer layer, to start a hole on the inner layer. And I just find it easier to work with. I'm not having to keep a seam allowance folded under, there's a nice folded edge to work with that isn't going to unfold.
As far as those corners... I can definitely see the need for a tutorial...
I sew my binding (for the entire quilt) into one long strip, then do a folding method in the corners to get them to come out nice. The method I use is from Quilter's Complet Guide by Fons and Porter. ISBN 0-8487-1152-1
