I am demonstrating in Paducah this week and have been asked several times for a list of my favorite rulers. What do I have in my ruler rack besides the Stripology and the CGR24 – 6 1/2″ x 24 1/2″ rectangle?
The CGR48 is my favorite ruler when I am sub-cutting blocks or trimming a few half-square triangles. I work with five-inch squares a lot so this ruler is the perfect companion. The white line down the center of the ruler is at 2 1/4″. I use it to square up four-patches and is the width I like to cut my bindings. I use the angled lines to trim half-square triangles made from five-inch squares and sewn with a scant quarter inch seam. 
The CGR312 is 3 1/2″ x 12 1/2″. I just finished a bow tie quilt with over 500 three-inch finished bow ties. I used the centering line on this ruler to square up the blocks instead of a 3 1/2″ square. The length was easier to hold onto and protected my hands from the rotary cutter blade. The centering line at 1 3/4″ is also the width of strips if you are making the eight-inch log cabin blocks with the Log Cabin Trim Tool – an added bonus!
And then there is the CGR212 – the 2 1/2″ x 12 1/2″ ruler. Once again I like the added length to protect my fingers when squaring up blocks to 2 1/2″. But my favorite feature? The centering line at 1 1/4″. I use that line to cut 2 1/2″ strips in half when making four-inch log cabins with the CGRJAWMN4 or mini pineapples with the CGRJAW3MINI.
What rulers are your go to rulers – and why?
I show and love the 3 1/2″ x 12 1/2″ quick trim ruler constantly. I use it for cutting the angles on binding strips, making circles and many blocks in patterns use 3 1/2″ strips
My favorite 6 1/2 by 12 1/2!
I vote for the CGR6 – 6 1/2″ square. I have three or four of them – in my go bag, on the ruler rack, beside the sewing machine.
