Introducing DecoBob 80wt Cottonized Poly Thread

This thread line has been around for some time and it’s been making waves in the sewing community. Designers Violet Craft, Sue Daley, and Laundry Basket Quilts have even made their own packs to include it. So, what’s the fuss about? Let’s take a closer look at how this thread can visibly improve your projects and its unique properties.

This thread is veeeeery fine, 80wt fine to be exact. As the rule goes, the higher the thread weight number, the thinner the thread. So an 80wt thread is actually quite small. But don’t worry, this little ant knows how to hold its own. Giving the thread a tug will show you that this little thread is surprisingly strong for its size! This is because it’s created using cottonized polyester.

Don’t let this name fool you, a cottonized polyester is actually 100% polyester, which is well known as a strong material to make thread from. But when it’s cottonized, it undergoes a treatment where all the stretch and shine is taken out of it, allowing it to not only sew really easily through your machine, but it also hides in the fabric a lot better. This matte finish in addition to its small size really helps make it blend in. And because it’s really strong, you have the ultimate bobbin thread. So even if your bobbin pulls through to the top, you don’t have to worry about it showing up.

WonderFil puts this thread on all its prewound bobbins because of these ideal properties. There’s a lot of really great reasons to use a prewound bobbin, so don’t forget to check that out in our other video, “6 Reasons to ALWAYS Use a DecoBob Prewound Bobbin”.

But it’s not only great in the bobbin, you’ll want to use DecoBob in the needle to improve a variety of techniques. Even something as simple as piecing.

Pretty much every sewer is going to piece a project at some point, but you can improve your results simply by changing the thread to use DecoBob in the top and bobbin. Because the thread is so fine, it allows the seams to sit flatter and tighter, which in turn makes it easier to match your patterns and line up your project pieces. It will also look and feel noticeably flatter. And if you’re piecing something with a lot of small, intricate pieces (we’re looking at you, Courthouse Step), this thread will make a huge impact on allowing the fabric to sit flatter. It’s amazing how much space the thread will take up in the fabric, and it shows!

This thread isn’t just limited to sewing machines. DecoBob makes a gorgeous machine embroidered lace. Because the thread is so fine, you can show off all those pretty little details found in lace designs. The lace will be additionally extra soft and supple to the touch.

You can find DecoBob in 36 colours. If you’re sewing with it by hand, we recommend using a #10 or #11 sharps needle, or a #9 or #11 short darner needle. In the machine we recommend using a 70/10, 80/12 microtex needle, a 75/11 or 80/12 quilting needle, an 80/12 topstitch needle, or a size 16 longarm needle.
