Needle size for invisible thread

What size sewing machine needle should I use with monofilament thread?


I suggest starting with an 80/12 in either a Topstitching or Microtex Sharp needle. As you become confident in your machine quilting skills, then I would move down to a 70/10 or even a 60/8.

The monofilament thread doesn't fill the needle hole like a thread made from several plies will. The plies relax after the stitch is complete and fill in the space.

The smaller needle makes a smaller hole which I like. But...

...I liken quilting with a 60/8 to quilting with a 'staple'.

They are fine, so very, very fine.

If you're free motion quilting and pull the sandwich too fast, they are easy to break. There have been days where I've literally broken a whole package of needles before I 'settled' into my quilting frame of mind, so I've always got a supply of these teeny needles on hand. Remember to stock up when they're on sale.

Thank you for your question.

Needle Confusion
by: Sam

I have a Singer Quantum 9960 machine. I just read a post saying, i should use 75/11 needle and use invisable thread. And also use microtek 70/10. I bought a stock. Now you say 90/ i forget, but its what i was using in the first place. For one like myself. Its very confusing who and what to believe. Plz not your fault but there has to be a way not to waist funds.

From the Editor:

Hi Sam.

Like most things in quilting, you'll get a number of different answers and solutions to most quilting problems.

What it really comes down to, is what works best for you in your personal circumstances, thread, fabrics, machine, etc.

Personally, when I'm doing invisible machine applique, I'll use a 60/8 which is pretty much like sewing with a staple.

A lot of quilters are not comfortable with that—because they're so fine, they're easy to break. And if you're not comfortable, you're not going to be a happy quilter. And if you're not happy, you're probably not doing your best work.

That's a disservice to you.

You can easily move up to a 70/10 for the same technique with pleasing results. Or even an 80/12.

My best advice is always to start with what you have on hand, changing the least amount of things to get the results you desire. If your combination of needle, thread, fabric, and the machine isn't getting you the results, then it's time to try something else. Next to tension settings, the needle is the easiest and cheapest to fix.

For my own expectations, I don't use the 90/14—it simply leaves too big a hole for my liking, but...

...if it works for you and you are happy with the results, it's not for me to judge and say you shouldn't use it. That would just be wrong.

So look at all the different suggestions you see and apply what you know about your own needs to choose which is the best option for you.

Look for the 'why' of the suggestion as is 'why did that quilter choose that'. Do the same conditions apply to you. Then it makes sense.

I hope this helps a bit. I know the Internet can be a confusing place.
