SA Measuring Wheel Review + Giveaway


One of the hardest parts when patterning bras is making sure all the pieces matched up. Because 1/8″ can be the difference between a bra fitting and not fitting, it’s so important that all seams equal. Do you know how many times I had to measure and remeasure in order to get all the pieces to be the same? And do you know how much time that took? Plus, with a dinky measuring tape, the measurements weren’t that accurate – I was never sure if I was correct or not. A solution came when I came across Claire’s shop, SACurve. Holy smokes, kids. Do you remember the Barbie doll aisle in Toy R’ Us? Claire’s shop was just like that.

Claire was kind enough to send me SA Measuring Wheel, which measures armholes, necklines, crotches, or  any curved line, and the 3/8th Mini Ruler and 3/8 Pattern drafter, which are designed to add, change, or mark the seam allowance location quickly and accurately. I was going to test the rulers and post a review, but Amy beat me to the punch and probably did a better job than I ever would (awesome job, Amy!), so hop on over to her blog to see the rulers in action.

As a giveaway, Claire is offering a mini and pattern drafter ruler and a SA Measuring Wheel! all you have to do is write in the comments below your contact information and how you would use these rulers. Contest opens immediately and will close on October 31st. Also, contest in open internationally. Good luck!

    I got the SA rulers when they were on special in July. LOVE! I really hate doing curves SAs with a straight ruler. I’ve since used SA to find seam lines on pattern traces, to add SA’s to an Ottobre pattern and even to add SAs to software patterns when I used the parabola to draw a curve..sadly you cannot use the offset function for it to make the SA in the CAD editor. Believe it or not, drawing them in with the SA curve is faster.
    I got the mini and regular curves at 5/8 in. because they are thicker, plus I can use the 3/8 printed line to add a 3/8 in SA. I’ve not heard of the measuring wheel before, but I currently use flexible rulers or occasionally the Dritz styling ruler to measure crotch curves, armholes, etc.

    sounds like the solution to all my time consuming grading problems. I teach kids, and I’d love to use these rulers to make my preparations go faster (they need the seam allowance marked, otherwise sewing in a straight line is very difficult.
    I believe from reading this that with this type of tools adapting patterns for their needs would go way faster.
    + I’d love to make myself some proper fitting bras!

    I bought the 5/8th ruler and I love it – I add seam allowances to burda patterns, to any pattern alterations I moght be doing and to draw curves. I would love to try the measuring wheel- the other day I was drafting a stand-up collar for a cape pattern and it would be convenient for measuring the neckline length!

    Sounds like an amazing resource! I would love to win it. My contact is: brigid(dot)boyer(at)mac(dot)com.
    I would definitely use it for drafting patterns, as well as adding seam allowance to japanese patterns.

    This would be SUCH a great tool to have around for anytime I alter a pattern. I always find myself fiddling around with my tape measure, and, yeah… not very accurate!

    I would end up using these rulers almost everyday! I am working on designing up a line of women’s ready-to-wear downloadable sewing patterns. These would be amazing!

    Aren’t these tools great?! I’m glad to hear you’re putting them to use patterning bras! (And, no need to enter me into the giveaway – I’ve got my own already!)

    I have Claire’s standard 3/8″ and 5/8″ curves and love them (for adding S/A’s, or from converting 5/8″ S/A to 1″ S/A for muslinning), but I really need the mini’s for working in my tiny armscye curve. Oh and anything to help with sleeve caps!!

    Since I moved from a hot climate to a cold climate,I have been trying to add sleeves to my favorite patterns. If I had one of these, I could stop tearing my hair out in frustration. And I wouldn’t need a hat!

    I broke down and bought some new rulers for drafting the slopers you teach on your website/blog; so exciting and challenging ( I wrote to you about those challenges; thank you for your input and encouragement), to make patterns again; haven’t tried it in over 20 years!! The rotten thing is the flexible, red grid rulers that I bought are 1/10 scale; I’ve never even seen 1/10 scale-not wonder my slopers were out! Alas,….I cannot take them back…Claire’s rulers would be super fantasticly helpful!

    WANT! want want want want. I would use these to put SA’s on my Lek0-Mail custom fit patterns and obviously it would allow me to sew 10 things in ONE day. Contact as per usual.

      could you use them for your shoe drafting?

        Natasha Estrada

        I think so because instead of SA we put lasting allowance on. Usually with a wing divider which is something I’m going to try with my clothing patterns.

    Ooo. This looks cool. I’ve been learning to make patterns and I’d love to try this out. I’m not up to bra-making level, but it may be in my future. 🙂

    Oh, they look fabulous! I’m a big pattern hacker so need to true and check things all the time. I’m dipping my toe in the drafting pond too so thes would be awesome for that as well!

    These would be sew useful when I (try to) Frankenpattern. I could actually use an accurate way to see if the sleeves from blouse A fit in dress B without some feeble attempt to just ‘eyeball’ it.
    Thank you for hosting such a cool giveaway.

    These would be wonderful when I do my sleeve and armhole alterations. It would certainly be more accurate than my “measuring tape along the curve” method, to make sure everything will fit together.

    I would definitely use them to redo the crewnecks for all of those awful crewneck-shirts I bought in the early 2000’s! I should at least be happy that I still fit into them! My e-mail is vintagezest (at) gmail (dot) com

    I saw these when Amy reviewed them. I need this, like the other comments a measuring tape is not the best and when making things like lingerie 1/8 is a big difference. I have favorited the shop on Etsy and will go back and shop soon.

    Ooh, count me in! I’ve been sewing silky blouses and slubby knit Ts where I can fudge things a little (bu adding darts, gathers, or stretching one side a little bit). But I’m getting into bra-making and coat-making now…

    I use rulers for everything.I use ruler for drafting patterns, making sure my art work is accurate and for other measurements. But because I don’t have a nice curved rulers. I have been really hindered in my pattern drafting. But if I win I will be able to get on drafting skirts. I am sew excited. Thank you for the awesome giveaway.
