Easy 3 Thread Serger Hem for Stable Knits

Here is a quick and easy way to finish the hem of stable knit fabrics using the serger. I love this treatment for sleeve edges and collars because it finishes the raw edge and eliminateds the bulk of the knit. Make sure to use it on a stable knit fabric that doesn't curl such as an interlock or French Terry.

Set the serger for a 3 thread flatlock stitch with the width at 3.5 and the length at 1.75. Test on a scrap of fabric to see how to set the differential feed. I have mine set to 1.5. The key for good coverage is to use wooly nylon in the upper looper.

The video tutorial below shows step by step how to thread the serger (my air threading won't work with the wooly nylon) and the settings I use.

I have used this technique on the collar on Rosebud below.

Happy Sewing!
