Here's my tutorial for how I make binding and bind a quilt. It's really not as hard as everyone makes it out to be. I learned from the back of a quilt magazine years ago (at least I think that's where I learned this method).
First I cut my strips at 2 1/4". This gives me plenty of fabric to sew the binding on to the quilt front with a 1/4" seam, and have enough to cover my machine stitches on the back. I measure around the edge of the quilt and add 20" or so to make sure I have enough strips cut.
Next I sew the strips together, right sides together, at a 45 degree angle, trim to 1/4" and press open. Then press the whole strip in half, wrong sides together. (I need a few more pictures here, but forgot to take them.)
Lay the binding strips down on the quilt. You're going to mark/trim them so that they overlap each other by 2 1/4" (I need to redo my photos for this part--I had an extra 1/2" that I didn't trim).
Hope this little tutorial helps!
(Note: Here's the tutorial on APQ's site, but some of it is a little confusing. Hopefully the two tutorials combined will make sense. http://www.allpeoplequilt.com/how-to-quilt/finishing/joining-binding-ends)
