by sewing the raw edge to the front, you get a more even seam. i like wide binding so i cut 4 1/2 in wide, fold over wrong side to wrong side
which makes 2 1/4 in and folded over to the back gives you a 1 in binding even on both sides. use matching fabrics if you use a border, this makes the quilt border blend with the binding also match your thread to the border and binding so that the seam colors match, if you make a slight mistake in sewing on the binding it wont show as bad or hardly show at all. only you will know the difference. we look at our quilts close up beginning to finish and see our mistakes. observers only look at the overall finished product and only see the beauty and fine craftmanship. think about this.
