The Stripology Squared, a slotted ruler by Gudrun Erla, has cutting slits every 1/2 inch so each strip you cut is the exact same size EVERY time!
Creative Grids Stripology Squared Quilt Ruler - CGRGE2
The Creative Grids Stripology Squared quilt ruler has all of the features you love in the original Stripology ruler and makes squaring upblocks a breeze. The smaller size is easier to manipulate and is more portable so it is the perfect choice when traveling to classes and retreats. Because the slots are longer to accommodate larger blocks, it is excellent for cutting wider fabrics. Follow the squares at the bottom for 2 1/2 inch cuts; follow the stars for 1 1/2 inch cuts - no math required.
