How do I know which tension—needle or bobbin—is out of sync? I can see the top thread on the bottom of my quilt sandwich. A trace to loops to tangled loop messes.

Thank you, Vivian, for supplying pictures of your problem. They help SO much!!!

OK, let's get down to business. First, check all the basics...

  • Put in a 'new-out-of-the-package' needle. Needle points are fragile, especially the ones on the MicroTex Sharp and quilting needles simply because they are so fine. A damaged needle can through off your tension adjustments.

  • Re-thread your sewing machine completely, sometimes the thread pops out of the tension disks. I don't believe it's the tension disk in your situation because then ALL the tension would be bad. You'd basically have a continuous bird's nest or 'thread throw-up' on the backside. But it doesn't hurt to double check.

  • Check that you've used all the thread guides on your machine. Double check that last guide just above the needle. This one gets missed sometimes. All the guides along your thread path add a bit of tension as your thread winds it's way to making a stitch.

  • Make sure that you have a nice, tightly wound bobbin that looks smooth. Once in awhile, my machine just plains winds a crappy looking bobbin. You'll be able to tell because it looks sloppy. If that's the case, I find that I can add a bit of extra tension by letting the thread run over my finger as the bobbin fills.

  • Finally, make sure that you've put the presser foot in the down position. Even though you're free motion quilting with a darning foot, and the foot hops along instead of pressing down on the quilt sandwich, putting the foot down is what engages the tension disks as you sew.
Now test again. If you still are having problems, we'll continue by...

Adjusting Your Needle Tension

While it is possible that a tension problem is solely attributable to your bobbin (see NOTE below), my experience is the majority of problems are solved with adjustments to your needle tension.

Since your needle thread is showing (looping) on the backside, needle tension is too loose.

To tighten it, increase the number on your tension controls. If the control is a knob, just remember 'righty-tighty'. Adjust by one number at a time and test. Repeat until you're satisfied with your quilting stitches.

Tension is Wonky on Curves

Now, if you have loops on curved areas on the backside of your quilt, that is called 'eyelashing'. You'll find that the rest of your quilting stitches look pretty good, just the curves have problems.

In that case, first try slowing down as you go around the curves.

Sometimes we like to 'whip around' a curve...it kind of feels natural...but slow down and try to move the quilt sandwich at an even pace, while keeping the stitching speed steady, too.

Be prepared.

It does feel un-natural to stitch this way at first. However, as you get used to moving the quilt sandwich at an even speed it becomes rather zen-like and peaceful. (OK. I don't mean to sound New-Agey, but I don't have a better description of the feeling.)

The other thing you can do for eyelashing is to 'tweak' the needle tension just a bit. You still want to keep the rest of the quilting looking nice, but you should be able to tighten it just a bit and that may do the trick.

NOTE: Now if your needle thread was pulled to the backside, but not looping, and the adjustments described above didn't correct the problem, then adjust the bobbin case tension screw.

First mark the orientation of screw before you make any adjustments. Then you'll know the position to return it too when you are finished.

To loosen the bobbin tension, you'd turn the screw an eighth of a turn to the left (remember 'lefty-loosey'). Stitch on a practice sandwich to test and keep adjusting until you are satisfied with your stitches.

Vivian, I hope I've been able to help.

Thank you for your question...AND for supplying the pictures...that helps a lot!

FMQ Gone Mad
by: Wendy

Hi,

I have stippled quite successfully before, but all of a sudden my machine has gone crazy.
It hasn't made hardly anything since the last service. It is a Brother Quattro Innovis 6700D.

I have lovely Superior Topstitch thread in both bobbin and top. Brand new needle. So off I go, first everything looks ok when I am going in a forward motion but as soon as I start to turn, I lose control, the machine skips stitches.

In fact sometimes doesn't even get picked up from underneath at all. But when I start to move straight and forward, it's ok again.

I have tried it using the FMQ Button and then taking that off and just putting the suture length on .02 which is the smallest, and tension on 3.5 but to no avail.

Can anyone help please?

From the Editor: Hi Wendy! It's frustrating when your machine goes wonky. I know. I've wanted to throw my machine out the window from time to time.

You've got lots of good information in your question.

Try this. Install your regular presser foot, raise your feed dogs and stitch...straight. Are the stitches skipping then? If they are, then I'd take the machine back to the dealer. I'm thinking there might be a burr on the needle plate from hitting a pin or that something is a bit off on the timing.

If there's no problem stitching straight, then first thing I'd do is completely rethread and install your FMQ foot just to make sure everything is in order.

Now try a bigger needle with a bigger eye. You'll find the largest eyes on both the topstitching and metallic needles.

If that doesn't do it switch to a straight stitch needle plate (throatplate). It's possible that for whatever reason, your fabric is flagging and preventing the loop on the back of the needle from forming either at the right time or properly. That would produce skipped stitches, too.

Finally, try slowing down your hand speed a bit. If you're moving the quilt sandwich too aggressively, you may be pulling on the needle just a wee bit. Pulling it a bit out of place would also impede the proper formation of the stitch.

If those don't work, then I'd go back to the dealer since it was just in. Take samples to stitch on with you.

I hope this helps.

Free Motion Problem
by: Christine

Hi Sharon,
Have you solve your problem on skipping stitches/not picking up bottom thread? I have the exact same problem and am baffled because I've change needles, re-thread every thing possible. If you've solved your issue, do you care to share it with me?

Thank you.

Free motion problem
by: Sharon Switalski

My free motion quilting keeps skipping stitches and sometimes doesn't even pick up again. I have tried readjusting the tension, have a new needle, have rewound the bobbin and re threaded.. My machine doesn't do this on any other sewing. What is my problem?

Free motion no starter
by: Anonymous

HI!

I have tried unsuccessfully to get started with free motion quilting. My problem is that the bottom threads gets terribly tangled up right away - I have tried adjusting the tension but with luck...any help would be appreciated.

From the Editor: I'm not quite understanding (not enough caffeine yet, I guess!)

If it's just the thread tail that is getting all snarly, you need to bring it to the top before you start any of the stitching. Click here for a step-by-step through the process.

If it's a big glob of thread throw-up, I suspect that the bobbin thread isn't properly seated in the tension spring on the bobbin case. If there's no tension on the bobbin thread, it's just plain nasty. Pull out your manual to double check the bobbin threading instructions.

Let me know if this helps.
