Amanda Murphy rulers

I've had a great day playing with Amanda Murphy's Every Semicircle quilting rulers and the Every Wave ruler. The Every Semicircle is very interesting and versatile, I've only just started!!

The pattern I have tried is quite simple, forward over the top curve of the semicircle and backwards under the bottom curve. One quilt was done with just one sized template, the second quilt was done alternating between two different size semicircles. It gives an interesting pattern, almost looks free form / radom, but its not. Lots of possibilities.
