The Jemma Tunic from Sinclair Patterns just released this past Thursday, September 13. With a stylish, asymmetrical cowl and multiple options, it’s a sewing pattern that results in the perfect addition to any fall wardrobe.

Testing the Jemma Tunic

I was privileged to be chosen for the Jemma tester team. This is the third time I’ve tested for Sinclair Patterns and this test, in particular, was a really great experience. One thing I love about Sinclair is that each pattern comes with three height options; petite, regular and tall. At 5’10 — I fall into the tall category. With the tall version of the pattern, I don’t have to adjust for my height and the fit on the Jemma is perfect. The sleeves are actually long enough! (Not something that ever happens with ready to wear clothing.)

Oxana Sinclair did a lovely job on the design and drafting of Jemma. Literally, the only thing that was changed during testing was the length of the cuff. The instructions are easy to follow and I was surprised by how quickly the tunic came together. 

Sizing Notes

When I made my first muslin of Jemma, I chose size 16 because I was in between sizes 14 and 16 — the 16 it was closest to my bust measurement. My bust and hips are usually one size, while my waist is usually a size up. Since this was relaxed around the waist, I didn’t grade. 

Size 16 was too big. In the tutorial, Oxana recommends sizing down. She was right (of course). After my initial muslin was too big, I went down a size to 14 and the fit is perfect! Making a muslin is so worth the extra bit of time whenever you make a new pattern. Every body is beautiful, different and unique — so taking the time to learn how things fit pays off in the end. 

Fabric Choice

Jemma works with several different fabric choices such as sweater knits and French terry. I used a light hacci sweater knit for the main body of my Jemma. The collar and cuffs are of a drapey mystery knit — similar to rayon spandex, but a bit heavier and more sturdy feeling. The collar works best with a fabric that has a lovely drape to it. 

Pattern Notes

Fit: Once I determined that I should do as the instructions say size down, I loved the way Jemma fit. I find the shape very flattering on me as it compliments my curves without showing off my mom tum.

The Pattern/Instructions: The tutorial for Jemma was very easy to follow. I wasn’t sure how the collar would work since I haven’t done one in this style before, but the instructions laid it out step-by-step in an easy-to-understand way. There are petite, regular and tall options. The pattern is made to be either trim or trimless — so you really can pick your preferred way of putting it together. (I love trimless!) Sinclair Patterns also include an A0 version if you want to print through a copy shop instead and skip all that tedious gluing or taping. The pattern doesn’t include cut charts for the bands (I like having that option) but does have the pattern pieces included.

Construction: The Jemma tunic went together easily. I think the trickiest thing is the collar — which if the instructions are carefully followed turns out just fine. The cuffs are meant to be snug, so they have to be pulled quite a bit when sewing them on to the sleeves. Everything else is very simple and straightforward. 

Nursing Friendly:  When the Jemma is made with a more stretchy fabric and the fabric in the collar has good recovery, it works very well for breastfeeding. I had no problems pulling it down to nurse my daughter. Stylish and nursing friendly? That’s a win!

Final Thoughts

The Jemma tunic is my favorite Sinclair make to date — though Xena is a (very) close second. I loved it so much that I actually hacked the free Ringer Tee from Brindille & Twig to make one for my baby girl! I need to add more sweater knit to my stash, and when I do, I will add another Jemma to my wardrobe. I’m also planning one as a gift for my Mom. It will be just perfect for her!

On another note … my husband says my Jemma makes him think of Star Trek and says I should replace the button with a Star Trek themed one. Lol!

The Jemma is ON SALE for a limited time. Like it? Grab your copy and sew one up! Then share it with me! I’d love to see your version!

  1. I love the look of the Jemma. Your colors are really pretty. My question is, in your opinion, could a little past beginner make this? And I have sloping shoulders as well. Are you comfortable offering suggestions? Thank you

    1. Thank you, Brenda! The Sinclair website lists Jemma as a beginner pattern, so it’s definitely worth a try! I can’t really help with the sloping shoulders, as that’s not an adjustment I’ve made before, but I’ve found everyone in the Sinclair Facebook Group (https://www.facebook.com/groups/sinclairpatterns/) to be super helpful and I know they could answer any questions or help with any fit issues.
      If you have any questions along the way about sewing knits or the construction of the Jemma, feel free to drop me a note. I’m more than happy to help. 🙂
      All the best,
