I have more rulers than I will ever need. (I buy when the spirit moves me and the coupons are available). But the handiest one of my impulse purchases has been the 2 1/2 inch "Binding Buddy" Its 2 1/2 by 30 with a 45 degree angle cut on one side. I know I can do exactly the same thing with my original 24 x 6. But I can line up and cut so much straighter and faster with this. I think it also comes in 2 1/4 width.
