I heard about these rulers last year and then was told to be careful because they bend easy or can get distorted.  I worked on different case ideas, and none of them were satisfactory until I designed this case that uses the Kraft-Tex paper fabric.  This fabric is durable and washable, and it has a unique look.  I added a heavy mat board insert to give the ruler stability.  The case is available in my Etsy Shop

I have heard some people say that you have to measure over 4”, not just 1”, to get correct gauge.  This is true, but you can do that with the Ann Budd Handy Gauge Ruler.  Just use the ruler – it is 9” long – and count the stitches over 4”.  After I test my gauge over the 4” and begin my project,  I use the stitch markings for a quick gauge check periodically to ensure I am staying on gauge.  Also, when I am knitting a swatch, I don’t want to wait until I have the whole thing done to measure.  I can use the stitch markings on the Handy Gauge Ruler after I am a few rows in to see if I am close to gauge.  If I’m not, I can start over before I go any further.  After I have finished my swatch, then I can use the ruler measurements to check my gauge over 4”. 

Lastly, for projects like cowls, shawls, or scarves, I like to have a quick check of my gauge to ensure I’m not going over my yardage requirements, especially on projects that use all the yarn called for.  It would be terrible to knit in a larger gauge and run out of yarn!
