Are You a Leftie?

We’ve designed a true left-handed ruler just for you – with the numbers mirrored from the right-handed version so that you can cut the correct way for you!

Trim 4.5” quilt blocks quickly, easily, and more accurately than ever by using our new Sew Magnetic 4.5” x 4.5” Ruler – a non-slip, adaptive way to cut!

For use with the Sew Magnetic™ Cutting Mat of your choice (sold separately, or purchase a complete system kit!).

This Sew Magnetic ruler is a crystal-clear 4.5" x 4.5" acrylic ruler with turquoise and black imprint – the 1/2" numbers are in turquoise boxes, and the 1" numbers are in black boxes.

Additionally, there are ⅛” and ¼” markings, as well as 30°, 45°, and 60° guides on it.

We designed it so you can use it right-side-up for whole-inch cuts or flip it around 180° for work needing half-inch cuts.

The magnets in the ruler are strong enough that your project doesn't slip, and light enough that the ruler also easily shifts where you want it to – and, it has a bit of non-slip to make it even more secure when cutting the slickest fabrics (and kiiiiinda beautiful, if we do say so ourselves!).

With the Sew Magnetic ruler and mat, you don’t have to push down very hard to hold everything in place – it's a more accurate and ergonomic way to cut than ever!

Please note: Final product may vary slightly from the photos and renderings shown.
