Reduce your rotary cutting time up to 75 percent with the Stripology XL by Gudrun Erla. This slotted ruler has cutting slits every 1/2 inch so each strip you cut is the exact same size EVERY time! Cut an entire half yard of fabric or a fat quarter without ever moving the ruler. Follow the easy-to-read markings: squares for 2-1/2 inch cuts and stars for 1-1/2 inch cuts - no math required! Cut eight 2-1/2 inch or fourteen 1-1/2 inch strips at one time. Need to cut in 1/4 inch increments? No problem, just follow the chart included in the instructions and use the 1/4 inch line on the ruler.
