Decorative Thread for Serging

It’s National Serger Month!

Baby Lock Triumph Serger

Using decorative thread for serging in the loopers (and even needles) transforms your serger from functional to decorative, thereby expanding the capabilities you have with your serger. To kickoff national Serger Month, we’ll dive into the fun threads you can use with your serger to breathe new life into your projects.

The Baby Lock Triumph serger, shown above, is fresh out of the box, just waiting to test out all sorts of fun threads!


Even if your seams are functional, rather than decorative, you can still change up the thread colors and showcase a different color for each needle and looper for a little something special on the inside of your garment.

Poly Deco™ thread is 40 wt. and is a great choice for an all-purpose type of serger thread. Plus, it comes in loads of pretty colors to match your fabrics. Try it with a wave stitch on exposed seams and really let the thread shine. Once my serger is set up, I can’t wait to try this stitch! Have any of you tried it yet?

Sulky 12 wt. Cotton Blendables® are particularly pretty in the loopers paired with 30 wt. Cotton Blendables® in the needles for rolled hems or edge finishes. 


You’ll also love how Sulky Invisible Thread stitches in the needles, with Sulky Original Metallic Thread in both upper and lower loopers (not necessarily the same color). 



A fun edge finish on cuddly flannel or soft baby blankets is to serge the edges using Sulky Filaine thread. This thread is 100% acrylic, 12 wt., comes in lots of rich colors, and feels super soft to the touch. Use Filaine in the loopers, paired with 30 wt. Sulky Cotton in the needles for a softness that can’t be beat.

Try using your serger for more than utilitarian seam finishing! Quilt-as-you-go quilts and table runners can be made entirely in a serger, including the binding. Check out different bias binding attachments for your serger to expand your machine capabilities.

Other specialty serger feet can assist with many more fun techniques at the serger, too! Look to your machine brand website to discover the options available to you.

    I LOVE Sulky 12 & 30 wt cottons for my Triumph. I use them extensively! I have Two full boxes of them and I want more! The decorative effect is perfect for soooo many things. I also use all of the other threads in my serger and in my embroidery machine. Even my older thread seems to work fine for embroidery. Thanks

    I’ve been using decorative threads in my serger for a while now, it’s very fun to see the different outcome!

    I love using Sulky blendables and metallics in my serger! I’ve stitched towel edges with Christmas colors then added holiday embroidery designs! It’s great to see reactions from others when they see this! I’ve used them with the wave stitch too!

    This is great information to know! I love the idea of metallic finishes for hems. And I enjoy creating handkerchief hems and variations so this would be the finishing touch that my garments need to be complete and decorative. Now all’s I need is a working server. I just have a Husqvarna Viking emerald right now, it’s a great machine for sewing but I don’t think it can be a server too.
