Finishing the vest seam allowances

Does anyone have suggestions on how to finish the seam allowances on the quilted vest? Since they'll show, I like them to look nice. This is the second time I've made this; the first time, I think I just did a simple zig-zag. Often I just fold under the raw edge, but the quilting will make it too thick for that. I'm considering using some of the bias binding to bind the seams. What do you all think?
