Description
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 quilts.
