I only have the starmaker 5, 6, and 8. Plus the Flynn double wedding ring templates. I haven't seen a need for other templates. I have a 3.5 x 24" ruler (broken down to about 19 inches), and a curvy ruler for a specific block that hasn't been used for anything else. I think a twister ruler/template could be useful. You need to have at least one ruler, and it has most of the angles that you could need, except for the starmaker 5. (I'm fascinated by 5 pt stars, 10 pt stars. .) I would buy all that i have again, except the curvy ruler.
