Ruby Ruler - 5" Square

Used to see if a color on a fabric is considered "light" or "dark." Works best if you hold the ruler up towards your face, rather than placing it on the fabric itself. This was a gift requested by my mom who saw my aunt using it.

It is really wonderful to find what is really bright!

I bought this ruler as a gift for a sister who quilts. It will be helpful when comparing fabric color values. Glad I found this handy 5” ruler.

I love my new Ruby Ruler! It is so functional!

Great for squaring up.

Watched video on it and it is amazing. Can’t wait to use it.

Has great lines ... measurement and angle lines, that is! Also, the color valuation is priceless! Love this tool.

Excellent for making squares

Had made some doll blanket squares and needed a 5" square ruler. Made my project so much easier to assemble.

I love that the ruler is red and I can see the negative color in my fabrics. And it’s just a super cute red ruler also
