Made in the USA with high quality acrylic and precision measurements ensuring accuracy for your quilting, sewing, patchwork, and crafting projects. Creative Grids exclusive non-slip grip allows you to easily slide the trim tool over the fabric until positioned correctly. Then, when slight pressure is applied, the grip holds the trim tool in place, eliminating slipping while you cut. Easy to read black and white markings. Strip widths and center square measurements are printed right on the tool. One round of logs is made up of two skinny strips and two wide strips. Each round of logs is trimmed to size before the next round is added making every block the same size when completed. To trim, place the appropriate centering square on the ruler over the center square of the block and trim two sides. Rotate the tool and the block and use the other centering square for the same round to trim the last two sides. Comes with fully illustrated step by step instructions.
