How Fun!!! Don't throw these around though. These rulers are
for curved crosshatching. I love the look of curved crosshatching but I didn't
have a ruler that had different increments so I could do it 1/2" or larger apart.
These rulers have increments of 1/4" up to 1 1/4" so you can have a choice of how
far apart you want your lines.
They also have the increments from the concave
as well as convex curves for easier handling of the rulers next to the
machines. These rulers have different curves for how curvy you may want to be.
They are based on a 12", 15", and 20" circles.
