I so hate to see people struggling to make HSTs. It isn't hard at all to make them my way. It is quick and easy and you can make tons of them without buying anything except your fabric.
If bias ia a problem then spray with sizing and bias won't be a problem any more. It has never been a problem for me.
I cut strips and sew them together and have a stack ready. You do need a mini cutting mat for ease of cutting and a template. You do have to pay attention to cutting accurately. But this is so easy to flag sew the strips and then to cut in an assembly line fashion and you can make scads of HSTs in a short time. No dog ears no recutting.
