If I put the hsts upside down, I could pick one up with each hand, and nest the seam, and start with the part that needed to match. So that it wouldn't shift under the needle.
I needed to add a plain square to the end of a set of two hsts. I set them like this in front of me, with the open end toward me.
I could pick up the triangle set with the open edge facing me with my left hand and the square with my right, and fee them through. One movement.
After all of them were done, it was time to add the plain square to the other end.
I didn't iron until I had them all together. And yes, those were my jammies, before the world was awake. A happy time to sew.
