Reduce your rotary cutting time up to 75% with the Stripology XL by Gudrun Eria. 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" cutes and stars for 1-1/2" cuts- no math required! Cut eight 2-1/2" or fourteen 1-1/2" strips at one time. Need to cut in 1/4" increments? No problem, just follow the chart included in the instructions and use the 1/4" line on the ruler.
