You will be so surprised how easy it is to sew a cute little pencil skirt with knit fabric on your serger. In this project, you will learn how to draft a pattern, add an elastic waistband, and hem your skirt. You’ll also get some tips for working with knit fabric, which can sometimes be a tricky fabric if you’re not used to it.You’ll find that a knit skirt can be such a versatile (and comfortable!) addition to your wardrobe that you’ll want to make one in every color of the rainbow!

Measure Skirt LengthStep 1: Measure from where you would like the skirt to rest on your hips to where you would like it to stop at the hem. I like mine right below my knees, which is 23” long for me.
Measure HipsStep 2: Your hips are the widest part of the skirt, so measure around the widest part of your bottom! My measurement is 37”.
Step 3: Now we need to make our pattern piece for our measurements. We would like the skirt to stretch just a bit across our hips for a good fit, so we are going to cut a rectangle that is 37” wide. When we sew our seam up the back, we will LOSE about an inch, which will make the skirt 36” in circumference, and therefore, stretch a bit. This is called negative ease.The rectangle should be 23” long, + 1” for the top waistband seam allowance, and 1” for the hem. So, the rectangle should be 37” wide and 25” long.
We are going to cut the fabric on the fold, so let’s also cut our pattern width (the hip measurement) in half. Our pattern piece should be 18.5” wide, and 25” long. Note I wrote “Place On Fold” on the edge to remind myself!Notice how I matched up the stripes as I folded it. If you’re using a striped fabric like me, check out this video for some pointers:

Cut Out Skirt
Step 4: Now it’s time to cut out your pattern. If this was a cotton, I would just use my iron-off pen to draw this pattern onto the fabric, but a knit is so shifty and stretchy, it is much better to pin a pattern to the fabric to keep it in place while cutting. Notice my edge is on the fold!
Sew Up Side Seam
Try Skirt OnStep 8: Before you do the waistband, this is a good time to try your skirt on. It will pool around your waist area, but should fit nicely in the hips. If it’s too big around the hips and you would like it tighter, run it through the serger again, cutting off the seam you sewed previously. Repeat this until you get a nice fit that you are happy with!

Pin Elastic to Waist
Step 9: Measure your waist, which is the smallest part of your middle. My waist measurement is 29”. I want my skirt to sit down on my hips a bit more, so I am going to add 1” to make it a bit bigger. My elastic piece should be 30” long.Now overlap the ends of the elastic by ½”, being careful not to twist, and zig zag back and forth across the overlap several times to join them in a loop.
Step 11: Put the elastic ring inside the skirt (on the right side of the skirt). Match one of the pins with the side seam of the skirt and pin into place. Then, match the other pin on the elastic to the pin on the skirt. This will divide the elastic evenly across the skirt waist.
Stitch Elastic to Waist
Step 14: With the elastic underneath and the fabric on top, serge the elastic evenly to the skirt by pinching at a pin and PULLING the elastic toward you to stretch it out. Make sure and watch the fabric so you only pull the elastic enough for the fabric to lay STRAIGHT, not STRETCHED. Only the elastic should be stretching.

Step 16: Now turn your skirt right side out. The elastic should now be on the OUTSIDE of the skirt. Turn the elastic back around to the INSIDE of the skirt, and pin it down that way all the way around. You will only need to pin every 5 inches or so, since we are going to stretch as we sew again.
Step 18: Now, a knit does NOT have to be finished! If you look at many maxi skirts in the store, the edge is just cut right off, and there is no seam! Because it is a knit, it will not fray! So, you COULD be done at this point. Me? I like it to look pro, so let’s hem it.
