Marti Mitchel Kaleidoscope ruler
Thinking of buying a Marti Mitchel Kaleidoscope ruler. She uses it for a two color type kaleidoscope and I want to use it with one large print fabric and will be making an octagon. Is this a good ruler to use for this type of kaleidoscope quilt and can it also be used for a stack and whack without making the smaller triangeles for the corners. Thank you
