Triangle-in-a-Square Rulers

The Triangle-in-a-Square Cutting Rulers make cutting and piecing triangle-in-a-square blocks easy.  Good Measure Rulers feature a special nonslip backing and clear markings in two colors.  Their design makes them easy to read and makes blocks up to 10-1/2” simple to cut!

You can find  tutorial video for using this ruler here.

I used this ruler to piece my Garden Party and Frolic in the Rain – plus many other – quilts.
