I printed off Amanda Jean's binding tutorial and sort of tried it out last night. Somehow I got the idea that I could just wing the first half, but no: not only was my strip not wide enough, also the ends weren't the right angle. You live, you learn!
But it worked out super-well and I am loving the result. This weekend I will hand-stitch the binding and then finish quilting next week. Yes, I know, that's backwards! But I don't want to drag around my machine and need something to do while away from home.
