Sew Square 10インチ定規 by Sew Kind of Wonderful

The lines are so crisp and easy to read, even in dim lighting, which saves me from making silly cutting mistakes. My blocks are finally coming out perfectly square without having to double-check every measurement.

This ruler has become my go-to for squaring up blocks. The lines are crisp and the special marks for certain patterns are a nice bonus. It’s a solid, well-made tool that makes my cutting more accurate.

I've been using this 10 inch ruler for a few weeks now and the numbers are so clear I don't have to squint. The extra pattern markings are actually useful for squaring up my blocks quickly.
