Love this ruler. High quality and easy to use. Also, the metal lip is very helpful.

You need one of these!

I have been making/repairing canvas on our sailboat and fishing boat for more than 15 years; marking cutting lines/hem lines has always been the most time consuming and dreaded part of every project. I subscribe to SAILRITE updates and bought the canvas patterning ruler as soon as I saw it! It works extremely well and is a brilliant tool- I wish I could have had one years ago. I also want to highlight the excellent service support provided by Sailrite. The first ruler I received was imperfect and the service department replaced it very quickly. Also the SAILRITE videos are simply outstanding! Too bad every company could not be more like SAILRITE- great products and excellent customer support and education!

A Professional Helping Hand


Exactly what I have been looking for.

This will get lots of use.

I know it will speed up the process of sewing professionally.

Though, being overseas, the price of postage made it pricey it will be well worth what it cost.

Patterning Ruler.

This is one of the best little tools I've ever seen. It's simple brilliant and the uses, the possibilities are endless. The best recommendation came from my husband:

"For me?" "Thanks, it'll be in my tool chest", and walked away with it. "Ah, no dear, that's not for you, now give it back!"

Buy one and save yourself time.


Used this with the awl to make circular place mats for my dinning room table. Together they worked flawlessly and made the process very simple.

Drawing circles is so easy now


Drawing circles is very difficult for me. I'm always in search of just the right size dinner plate, or tin can lid so I can just trace a circle. With the Patterning Ruler, I don't have to search any more. I love that it's acrylic so I can see through to my project, and it stays in place perfectly. It's so easy to use. I just received it recently and I've already used it on both fabric and my wood project.

Great little addition to the toolbox.

Another great little tool from Sailrite. Makes adding seam allowances simple on irregular shapes. Love the little metal lip when duplicating pieces.
