Add an Eighth Plus- 9 Inch Ruler

If foundation paper piecing feels like a lot of extra steps, the Add-An-Eighth Plus helps streamline the process. This wider version of the classic Add-An-Eighth ruler combines folding and trimming into one tool, making it easier to create consistent 1/8” seam allowances while paper piecing.

The tapered edge folds foundation papers cleanly and accurately, while the wider body is easier to hold and maneuver than the original version. Whether you’re tackling intricate mini quilts, sharp geometric blocks, or detailed paper-pieced patterns, this little tool helps speed things up while improving accuracy.
