Hi there!
I love sewing with knit fabrics but I know they can seem intimidating to some us of, especially when you don’t own or use a serger to finish off your seams. No fear! I’m going to share a quick and easy way to get a seam finish that is similar to using a serger and all you need is your sewing machine and the zig zag stitch! Let’s begin:
Step one:
Here is my 3/8″ (roughly 1 cm) seam allowance, as you can see I’ve used a smaller zig zag stitch to sew up my side seams as per the pattern instructions.

Step 2:
Snip your seam allowance in half.

Step 3:
Using your zig-zag stitch at the widest setting and a stitch length of about 3 (or whatever suits you!) position you fabric under the presser foot and just test out your stitch (manually) and make sure that when your needle goes to the left, it comes down right beside the farthest part of your original seam.

Then move your needle (manually) to the right and make sure that the needle falls just outside of your fabric.

Step 4:
Start stitching away, don’t forget to backstitch in the beginning and go slowly at first if you need to. If your fabric is fiddly under the presser foot gently tug on it to straighten as you sew.

Stop and check to see if it’s coming along nicely, you want to make sure that the thread catches the ends of your fabric, think of it as “left stitch on the fabric, right stitch off the fabric” (I just realized that I didn’t snip all my stray threads off…lol).

Step 5:
Finish it off! Voila!

How easy was that?! Now you try and keep on delaying that serger purchase you’ve been mulling over in your head (be honest we’ll all cave in one day!).
