OLFA® Square Ruler 16,5″ x 16,5″

This OLFA® square ruler is super big.  I use it to square up quilts as it gives me such a huge square I can be confident that it’s a 90° corner.  It is easy to read, with its black numbers on the frosted background.

And the ruler is easy to use, with its non-slip surface.

The ruler is great for squaring larger blocks, borders and for square designs.
