Wow, you are all so encouraging! Thanks!
I don't know the differences in the binding. I folded the binding so wrong sides were together, and sewed it onto the back, on a day that I shouldn't have been sewing (but it was the last class), and it looked like a drunken sailor had done it. Then I folded it over to the front, and machine stitched it down using the same serpentine stitch that I quilted with. I didn't like the little gaps from the curves, so I did a straight stitch as well. The blanket stitch is a great idea, and I should be able to reverse it.
I think if I measured the binding, it would be different widths at various points. I'll have to look at those tutorials!
