The 10in Wonky Log Cabin Trim Tool, designed by Jean Ann Wright for Creative Grids® puts a fun twist on a traditional block. This one is designed to work with 2-1/2in strips for both the logs and center squares making it precut friendly. · 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 make it easy to line up on your block for trimming. · After adding each round of logs, place the appropriate centering square on the ruler over the center square of the block and trim. · Strip widths and center square dimensions are printed right on the tool. · Comes with fully illustrated step by step instructions. · Scan the QR code printed right on the tool to view a how-to video of these features and to see the projects that can be made with this tool.
