Are all of your HSTs the same color combos, or are you doing scrappy? When I first started quilting the only "ways" were draw lines on fab, or use easy angle, like Bonnie hunter does. Now, pick your way......there is also triangles on a roll or thangles .......along with "start with square, draw lines....." They all work, if you are consistent in your piecing. You state you are trying to find the " quickest" way because you have 1000+ other things to do -- this, in my opinion, is something we don't do speedily...it is something we do to unwind, enjoy, feel a sense of accomplishment....., not just whizz thru to get to the next thing in line. So, sit back, take a deep breath, try each technique and see which will work best in this particular case and relish in the process!
