This 10in Log Cabin Trim Tool, designed by Jean Ann Wright for Creative Grids®, creates 10in finished log cabin blocks, Half Log Cabin, and Courthouse Step blocks with this Trim Tool Duo. Choose from the standard 1in finished strips or the 1/2in finished strips, or a combination of the two for endless design potential. · 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. · Two sets of strip widths and center square measurements are printed right on the tool. · Make Log Cabin blocks with the same width of strips, or combine the two widths for limitless designs. · 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. · Comes with fully illustrated step by step instructions. · Scan the QR Code printed on the insert to view a how-to video of these features and to see the projects that can be made with this trim tool.
