Depends on how many I need. If I need a lot, I use the grid method. I draw my grid size 1" larger than my finished HST and trim down to size after sewing. This ensures the most accurate units. Very similar to NJ quilters method only I make multiples at one shot, not just two at a time. If I only need a few I do NJ Quilters method or use a strip. I have also done many HST as leader ender project using scraps from FG blocks which I make using a square and a rectangle.
