I like this technique. It makes two at a time. Needs trimming.
Chain piecing will make it a lot faster. Just have to get all your
fabric cut and ready to go. I don't think QST's is a fast project.
If you think it's too time consuming I would suggest a different
pattern. Good luck.
You can use the Magic 8 method to make your Half Square Triangles
then turn them to QST's. That's how I would do it for a whole quilt.
Speeds things up a lot.
