Knit Luna Pants

Tips for sewing Luna in knit

As you may already know, I love sewing with knits (here’s my KNITS page), and I’m always interested in whether knit fabrics will work my patterns. All of my current women’s patterns are designed for woven fabrics, but occasionally I add knits to the suggested fabric list. Originally I wasn’t sure if the Luna Pattern would work in knit fabric, but then Kelli of Cut Cut Sew made one of her test pairs in knit and declared it a win.

Shortly after that, I found this super-stretchy grey heather knit at a local shop and decided to give it a try. As you can see, it worked quite nicely. They’re shown here with my Nani Iro tee from way back and my newly-painted garage wall.

These have become one of my favorite every day Lunas. I wore them last week to yoga and they were perfect because they stay put when I’m sticking my legs straight up in the air. Woot!!

Here are a few tips for making a successful pair of Luna Pants with knit fabric, along with some pics of my pair in progress so you can get an idea for what it’s like to make them!


Consider cutting a size smaller than you would normally wear.
I went down a size and these are still plenty roomy. Keep in mind that you’ll lose a little length both overall and in the rise. I compensated by folding over a smaller cuff elastic casing (1/2″ instead of 1″) at the hems to get back a little length.

Add knit interfacing to the waistband
Knits are easier to work with if you add knit interfacing! My favorite is this tricot interfacing from Fashion Sewing Supply; it’s stretchy and adds stability to make the waistband easier to work with.

Try Wonder Clips instead of pins
Some knits can get small holes from pinning (the sharp ends of the pins can puncture the threads and cause the fabric to unravel). Even if you’re not worried about that, pins can come out of the fabric easily due to the way that knit fabric stretches around when it’s being worked with. Wonder Clips (you can get them at most fabric shops or online) are great for holding everything in place!

Use a serger
I know it’s all the rage to say that you can sew knits without a serger, but these pants are SO MUCH EASIER to sew if you’ve got a serger. The seams will be more flexible, better looking on the inside, and the whole project will go four times faster.

One last thing to mention, though it’s pretty obvious: I added a twill-tape drawstring to this pair (it’s a mod you can find the instructions to in the How to Add a Drawstring to Luna tutorial). The buttonholes were a bit tricky to sew in knit. I’m sure there’s some tip for that I haven’t discovered yet, but I ended up sewing each buttonhole twice to reinforce the stitching. Should have used matching thread…live and learn.

  1. Game changer! Thanks for sharing what the tricot interfacing looks like- I keep hearing about it, and now I know what I’m searching for. These look really great- not your average “jog pant” look. Love it.

  2. Buttonholes in knits are waaaaay easier and look better if you do one of two things.

    1) use a patch of less stretchy interfacing where the buttonhole will be or

    2) use a stabilizer while sewing the buttonhole. I usually use a tear away stabilizer when doing them though I have had success with a dissolvable stabilizer or even just tissue paper (like used when wrapping gifts).

    The benefit of option 1 is that the interfacing stays put when the garment is done preventing the buttonhole from stretching or distorting during wear and washing. Option 2 is fine if the knit is fairly stable to begin with.

    Hope these ideas help!

    • Thanks for the pointers, Lynn! I agree, I always use interfacing when I sew buttonholes!! 🙂
