I have some of Marti Michell’s templates and yes they can. You’ll just have to experiment and flip through some of her booklets that go with the sets again. I also have the 6.5” and 12.5” crazy quilt template sets put out by Shar Jorgensen in the late 1980’s (first acrylic templates I ever bought) that look remarkedly like this new set of rulers. Her set had more pieces for the block but worked so well for scraps.
