If you didn’t already know, April is National Serger Month! So in honour of this special month (because I love sewing with sergers) I decided to sew up a pair of leggings which are in my opinion the best thing that you can sew purely on a serger. Check out the post to see how I created these versatile leggings.

I traced out a fresh draft of our Knit Leggings Sloper and designed a pair of panelled leggings using the design template guide (found on the sloper’s pattern page). I always like to print off a bunch of these templates and draw a bunch of designs on them.

So once I decided on which design I wanted to make I got started on implementing the panel seam lines on the sloper. I had the design template right by my side so I could get the proportions right.


Once I had the panel line established on my sloper as well as the wide waistband level, I started to extract the different pieces. How I like to do this is to place tracing paper over top of the piece and trace the outer shape then add my grainline and seam allowance. Also don’t forget to label!

cutting out

I cut out one of the legging panel pieces in plain black spandex knit, and the other in a pleater/leather looking spandex with very similar stretch qualities. The key when adding panel seams to leggings and different fabrics is to make sure that they have the same stretch factor.

Sewing 1

When serging together panelled leggings you first have to assemble each right and left leg piece and then put those together. So I first serged the panel seams, attaching the plain and leather spandex together. This seam had many curves to it, so I made sure to pin! Then as you serge make sure to slightly stretch each layer the same exact amount. You want to avoid stretching one layer more than the other, because then you will end up with puckering and the seams not being the same length in the end!

Once each leg was assembled I laid the legs open, and right sides facing. I pinned and serged the front and back crotch seams together.

Now that the crotch seams were sewn you can sew up the inseam of the right and left leg in one continuous seam making sure to match up the crotch points. Simply start serging at one leg hem and end at the other.

Once the main body of the leggings are serged together, you can serge and attach the wide waistband. I unfolded the piece and serged together the center back seam. Then folded the waistband wrong sides facing so the two raw edges were together along the bottom. Then I pinned the waistband into the leggings matching up the center back seams. The waistband is cut slightly smaller than the leggings so you have to EVENLY stretch the waistband as you serge for the control top to lay nicely and not pucker in some places.

Leggings Project

Then all you have to do is finish the leg hems. You can do this by tacking the serging thread tails inside the leggings and to the seam allowance (since the spandex fabric doesn’t fray). Or if you want a more finished look you can turn in your added hem allowance and topstitch in place with a coverstitch machine (like I did) or use a stretch needle and zig-zag stitch on your regular sewing machine.

These are my finished leggings, and oh my are they ever comfortable! I actually wore them during Easter dinner and it was the best decision ever. I know I can wear them literally everywhere… to the gym, out on the town, or to a big holiday dinner (love how stretchy they are). You can see more images of my finished leggings here.

Happy Sewing!
