Four Patch Square Up

The Four Patch Square Up© Tool is the solution to wonky four-patch blocks. Like all the Studio 180 Design rulers and processes, this tool and technique will have you build your units slightly oversized and then quickly trim them to perfect shapes. The Four Patch Square Up© Tool is designed to work with units that finish to whole or half inch increments, from ½” finished up to 6” finished unit sizes. The tool’s perfectly engineered lines are designed to quickly locate and align with the unit center and the sewn seams, allowing for easy trimming on all four sides. The accuracy is amazing!

Your units will be the correct size. They will have seams properly positioned. And they will have edges that are straight , even, and square. No more guess work!
