The technique which uses bias bars gives a different look as the bias strip becomes 3 or 4 thicknesses of fabric after folding, stitching, re-pressing, etc. I actually like the look of the thicker bias but it really depends on how it's going to be used and your personal preference as to the finished look. I make lots of bias because I love to make Celtic designs (and teach it!) and Stained Glass type of designs.
