OLFA 12 1/2 x 12 1/2 Frosted Acrylic Ruler (QR-9S) - Non Slip Square 12.5x12.5 Inch Acrylic Ruler with Grid for Cutting Fabric, Sewing, Quilting, & Crafts

I like the Olfa rulers. They are easy to read with the marks you need but not too busy.

Good buy

Easy to read. Nonslip. Great for squaring up guilt blocks

As someone newer to quilting, I’m not always sure about products but this is a must in my opinion. Great way to quickly and efficiently cut squares etc for your project. I love Olfa products and this one is no exception.

Very easy to use.

Fantastic product

Love this ruler, little or no glare!

The ruler has less slip than others, and doesnt need extra stickies on the underside. Very easy to read through, and the markings are easy to see. However, I had assumed the frosted part would be on the top, since I was looking for a ruler that would not reflect the glare of the overhead lights in my sewing room. The frosted part is on the underside, and there is just about the same amount of glare as with the nonfrosted ones. I actually use it upside down, and will continue to look for a manufacturer that makes exactly what I want.

This ruler works fine for piecing quilts

A must have ruler for squaring up blocks.
