Get the most out of your Creative Grids XL Cat's Cradle Ruler by creating two extra large sets of squares and triangles. Trim the blocks using the XL Cat's Cradle Ruler to get triangle blocks without ever cutting a single triangle! The XL Cat's Cradle Ruler will glide over fabric until pressure is applied and then Creative Grid's exclusive gripper holds the material in place, thereby helping to eliminate slipping and miss-cuts. Thanks to the cutting requirements printed on the XL Cat's Cradle Ruler you can create eight different sizes, ranging from 4-1/2" to 8" finished blocks. Designed by Deb Heatherly and made in the USA.
