Non Mirror Combo Units Studio 180 Tech Sheet

Four Patches, basic units that seem so simple to make. Just stitch 4 squares together, either individually or with strip piecing and you?re good to go. But anyone who has attempted these units knows that they are notoriously difficult to make perfectly. Either the unit size isn?t quite right, the edges just don?t quite line up, or they?re just not quite square. Ugh. Even experienced stitchers encounter these problems.
The Four Patch Square Up© Tool is the solution. 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.
