Go easy and do as Jenny Doan does, iron squares on diagonal and use iron mark to sew, easy peasy and no marking. Cutting into triangle first your sewing on bias and could have distorted HST's or have to pin and that is a pain.
I made a bunch of HST's and chain pieced down one side and after a bunch were sewn, picked up first one and started down other side. Then cut them apart and separated them, fast and easy.
