This Gruuvy™ Square it up ruler is a versatile ruler that can be used for cutting strips, or squaring up blocks.  This ruler is slotted making it easy to center your design and cut around the edges.  Quickly square up and fussy cut blocks in quarter inch increments up to 12".  (This is the large size which measures 12"x21")

• Since the ruler is slotted, it's also great for cutting strips, squares and rectangles from yardage at 1/4" and 1/2" increments. 
• Save Time – Square up blocks up to 12 ½ inches; cut up to eight 2 ½ inch strips or 14 1 ½ inch strips without ever moving the tool, reducing rotary cutting time by up to 75%.

• Angled Cuts – Use the 45 degree and 60 degree angles to cut bias binding, triangles, diamonds, and parallelograms.

The Gruuvy™ Square it up ruler is made in the USA from clear, flexible material.  

Meant for use with a 45MM or 60MM rotary cutter.
