Creative Grids Stripology XL Ruler - The Stripology XL combines all of the features you love in the original Stripology ruler AND the Stripology Squared. This beauty combines the height of the Stripology Squared - so you can square up blocks up to 12-1/2in - with the width of the original Stripology so you can cut up to eight 2-1/2in strips or 14 1-1/2in strips without ever moving the tool, reducing your rotary cutting time by up to 75 percent. The 2½ inch increments are marked with squares; the 1½ inch increments are marked with stars - no math required! 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. We have added additional bells and whistles as well. There are 60 degree lines as well as 45 degree lines; 1/2in lines; and additional markings to aid in cutting perfect triangles every time. This ruler comes with fully illustrated step by step instructions.
