I have used both methods. As long as you starch your squares, you can use Jenny's method and not have a problem with bias edges. The starch stabilizes the edges. It is a great deal quicker than drawing lines and sewing on each side of it. I didn't go look it up, but I'm assuming Jenny's method is sewing around the outside edges of 2 blocks that have been placed with right sides together, then the square is cut diagonally twice, giving you 4 HST blocks. This is definitely my preferred way. Might be worth trying it. Also, as you sew HST blocks together, do not pull or stretch the edges as you sew. Let the sewing machine feed the fabric while you guide.
