I have 5 June Taylor slotted rulers in different sizes from 1/4" to 2 1/2" that I use daily. One of the rulers cuts eights. I love that ruler when I have to cut squares (e.g., 2 7/8"). The rulers make cutting strips and blocks fast and the correct size. I have the electric Accuquilt which I have used for cutting circles, flowers, and shapes without straight lines. Personally, I use the rulers much more often.
