I also bought three different square rulers. What? I had coupons–COUPONS, I tell you!
This is Omnigrid’s 4″ square ruler which I bought because of the all-over graph. It makes lining things up so much easier. I have a 6″ one with partial graph, but this is ALL graph! Plus, it has angle lines so I can do much more than square and half-square.
Omnigrid with graph and diagonal line. Isn’t it cute?
