Effortless Sewing: Master Adding a Thread Cutter to Your Machine

Oh, how the convenience of an automatic thread cutter on a sewing machine is something that feels so luxurious! To be honest, it’s hard to even remember the days before I had that feature on my machine. And then there were those times with a thread cutter just built into the machine’s side.

But, here’s the tea: I recently got myself a serger (I’m totally in love with my Brother 1034D serger ). And guess what? It doesn’t have a thread cutter! Yep, that’s right. I mean, I didn’t expect a built-in one for the price I paid, but I had hoped there’d at least be a manual cutter somewhere on it. Of course, there’s always the option of sewing over your thread chain with a serger, but oh, the thread jams I’ve had!

And while I tried keeping a pair of sewing scissors close by, let’s be real – I tend to forget where I put them.

So, in my quest for an answer to this thread dilemma, I stumbled upon a gem: the Singer sewing machine thread cutter. If you’re dealing with an older machine or a budget-friendly serger like me, keep reading, because I’ve got a treat for you.

The Deets on the Singer Machine Thread Cutter

The Singer sewing machine thread cutter is essentially a compact, round plastic gadget. The base is solid plastic, while the flip side houses a sharp little razor blade. The blade side is somewhat slimmer than the other.

You can find a pack of these beauties, three in total, on Amazon. Given time and usage, they’ll need replacing, so having spares is great. What’s cool is that they have an adhesive pad at the back, which means they stick to most sewing machine or serger surfaces. Just be gentle, because if you get too rough pulling threads, it might come off. But don’t fret! It’s designed this way to make replacements hassle-free.

Getting Your Thread Cutter Attached

So, where should you stick this handy tool? For most sewing machines or sergers, the left side of the machine head works best. Avoid putting it on the workspace to prevent it from catching on your fabric pieces. For my serger, I opted for the top left, close to the presser foot and needle. I suggest running a long thread chain to figure out the most convenient spot.

Now, I’m a creature of habit, so I love the blade pointing upwards. After deciding on the spot, simply peel the adhesive backing off and stick the cutter on. Voila! Now, snipping those threads is a breeze.

Thread Cutter In Action

For regular sewing machine threads, drape the two top threads and give a gentle pull. But, with a 3- or 4-thread overlock stitch, it requires a tad more finesse. Ensure you hold the thread’s end with one hand, wrapping it around the cutter, while using the other hand to secure the thread near the presser foot. This keeps everything tight and avoids the threads from going haywire. Trust me, when done right, it’s pure magic! ✨

My Verdict After a Month

One month in and I couldn’t be happier. That’s the very reason I’m sharing this with you all. The cutter remains sharp, hasn’t budged a bit, and it’s positioned so it doesn’t mess with my stitching. Sure, I might leave the threads a smidge longer than when using scissors, but hey, no more hunting for them!
