New Contact for SA Curve products

I have great news. Jan Reed with the Wooly Thread is the new distributor for the SA CURVE products. Inquiries for the rulers and wholesale information should be directed to her.
You all will love working with her.


Measuring an Armhole

Measuring an armhole is a tricky thing to get accurate because of the curved line. You have to start with the stitching line since the outer edge of different pattern curves can be different lengths for the same stitching line. Also, the stitching line to be measured needs to eliminate the beginning and ending seam allowances, so that comparisons to the sleeve head are easier. Once you understand the armhole measurement, measure the sleeve head to see what ease is drafted in. If you have a woven pattern and want the fabric to be a knit, you will want less ease (approx. 1/2 inch for a knit sleeve head) or if you want a jacket made in leather you will definitely not want a lot of ease in the sleeve head. I personally don’t like a front armhole of a knit top with less than 8 inches in length because it feels too tight to me.

Thanks for watching!!


Measuring Wheel Slideshow (Metric)

The Japanese metric measuring wheels are available on Amazon.

Measuring wheels are handy for measuring curved lines on patterns. Comparing an armhole length to a sleeve head will give you the amount of ease built into the sleeve. I find them especially handy if you have done fit changes and need to see how those changes affected your pattern.  Find on Amazon:

Pattern Drafter / European Patterns

Gracie says, “Check out the testimonials!”

Here are what people are saying about SA Curve Rulers:

I am a self-taught sewer with 37 years experience. I sew Burda, Knipmode, and other European patterns, including bra patterns and self drafted patterns that are especially sensitive to tiny changes – accurate seam allowances are essential.

I have traced with twin wheels, used rotary cutter guide arms, double pencil “holders” and even my own custom-constructed “Siamese twin” Sharpie markers. This beats every method hands down and allows me to use any marking tool or color my heart desires to mark the most accurate and consistent SA on any curved pattern. The method is super fast and accurate! The rulers are clear, with very useful markings.

It is a wonderful tool, and I am the happy owner of two SA curve rulers of each width. They were well worth the purchase price – I use them constantly. The site owner is wonderful and responsive – could not ask for a better product! Clearly (pun intentional) designed by a true sewer!


Hey Claire, I just wanted to let you know that I love using your ruler! I am working on an Ottobre pants pattern for my son and I was able to add the seam allowances so quickly. The pants are sewing up so well. I just wanted to let you know that I’m really happy with it!
