Make sure the chain stitch thread is threaded exactly as it should be, make doubly sure the thread comes off the bobbin vertically and runs through all eyes smoothly. Any faults in the threading causes extra tension at the needle despite what the tension is set on.
If this is not the cause then the needle depth and the looper timing needs checking.

SOURCE: thread wont overlock

When the thread breaks too often, try these, that goes for all sewing machines
1. Replace the needles,
2. Loosen slightly the tension of the needle threads.
3. The top threads are to thin,
4.The sewing (rotary) hook or looper, has burs,
5. Wrong threading

SOURCE: My Evolve serger is skipping stitches while using

First, change the needles making sure to use the el705 needle system. Second, make sure the subsidiary looper is engaged properly (plugging up the upper looper hole). Also make sure the needles are all the way up in the machine. This should do it or it may need to be adjusted but the Evolve is a very, very reliable machine. Hope this helps...

SOURCE: Serger stitch not forming right

It sounds like the timing needs to be reset by a sewing machine repair tech.

I am trying to teach myself to sew.... what is a serge stitch an how do I set my brother sewing machine to do it?


A serger (overlocker) is not a sewing machine. If you look at the inside seams of a purchased t-shirt, you will usually find a serge stitch that was created using a serger (overlocker). A serger/overlocker usually uses 3 or 4 threads to create that stitch. It also trims the fabric at the same time it finishes the fabric edge. The serge stitch is a chain stitch that, if you pull a particular thread, the entire stitch will come undone.

Your sewing machine is not able to create that same stitch. Your sewing machine may have what is called an "overlock" stitch, but it will use only 2 threads (the top and bobbin) to create that stitch. You would have to consult your owner's manual to see if it can make an overlock stitch.

Huskylock 936 will not form a 4-thread overlock stitch


It may be difficult to solve a computer controlled machine with as many options as the 936 serger. Stepper motors control many of the functions. You can check out this video I made 4 years ago to get an idea of where to look.

How do I create a rolled hem with this machine. I see the stitch width knob, but do I need to remove one of the threads for this?


Making a rolled hem on any overlocker is achieved in the following way:

use right hand needle only and top and bottom loopers. Turn stitch length down so threads are closed up (on mine this is 0.5). Your stitch length dial will be one on the right hand side near the flywheel usually. Loosen off the the top looper tension and tighten up the bottom looper tension (these are the right and 2nd right tension dials on front of the machine). On my Bernette I leave the needle at the usual 5, 2 on the top looper and 6.5 to 7 on the bottom looper thread. Move cutting blade position to the right so that you are trimming the fabric quite a bit wider than your stitch, this makes the fabric "roll" underneath inside the stitching to form the rolled edge or hem.

There is also another step that needs to happen where you change or remove a little stitch finger that sits in the pressure foot or just under it. On the Bernettes, you flick a lever to move this stitch finger back towards the operator so it is out of the stitch forming area. On some machines, it is a case of changing the little stitch finger which is screwed onto the pressure foot with a screwdriver.

I really don't know with your Necchi which it is but have a good look at the pressure foot, and around the blade cutting area and see if you can see a lever or check out the accessory bag and see if there is another stitch finger in there, it would be smaller than the one on the foot now. In effect, this finger sits out and the threads wrap around it to form your normal overlock but for rolled hem you want a much smaller finger in place to make a very little seam.

The other variable which makes a very neat job is to use a thread called "wooly Overlock" in the upper looper only. This thread when pulled under tension is tight looking but when you let it go, it fluffs out. So when seaming on a rolled hem it fills out the stitching and covers the edge of the fabric fully giving a smooth look. You can do it without but wooly thread makes a great job and you'll see it on all Ready to Wear seams usually for this reason.

If I am going to roll hem a fine sheer woven fabric like organza or chiffon I will change the needle to make sure it is nice and sharp and also ensure it is a regular point, not a ball point (I seam lots of knits so have ball points in most of the time on mine) Usually a size 80 is fine.

I hope this gets you going with your overlocker, I usually test stitch quite a bit with the stitch length at the normal 2.5 setting and adjust the looper tensions until I've got the stitch looking good, then turn it down to the very close 0.5, just to not waste a ton of thread.

I'm not sure how to thread my machine, I lost my manual elna lock pro 5Dc


I would suggest that you buy a new manual for this as your overlocker has 5 threads that need to be threaded up correctly to form a stitch and there are several different stitches that can be made with this model such as a rolled hem, chain stitch, three thread overlock, four thread overlock and safety stitch with three thread overlock, lots to learn.

You can buy a manual here for $USD14.99: http://www.sewingpartsonline.com/instruction-manual-elna-pro5dc.aspx
or this website has a copy for $USD10.
http://www.sewusa.com/Sewing_Machine_Manuals/Elna_Manuals/Pro_4DC_DE_Instruction_Manual.htm

Always well worth buying the manual and saving a lot of frustration trying to guess how things work and it adds value if you are going to sell the item.

You can get some general overlocker threading tips from http://sewing.about.com/od/sergersoverlock/ss/serger.htm which may help you too.

Trouble with my Huskylock 680D overlocker Tensions


You need to re-thread the serger.

Refer to the manual or open the front of the serger to see if the threading diagram is there.

With most sergers, you begin with raising the presser foot, then set the tensions to zero.

Begin the threading with the upper looper (curved looper), then the lower looper and the needles last.

Pull the thread under the presser foot and to the left side of the serger.

Set the tensions back to normal 4 - 5 usually.

Lower the presser foot and hold onto the threas tails as you stitch a chain. If the chain of the four threads is ok, you are ready to serge fabric.

My Evolve serger is skipping stitches while using the 4 thread safety stitch which is a chain stitch with a two thread overlock. Sews fine for a few stitches and then skips a loop which unravels. I checked...


First, change the needles making sure to use the el705 needle system. Second, make sure the subsidiary looper is engaged properly (plugging up the upper looper hole). Also make sure the needles are all the way up in the machine. This should do it or it may need to be adjusted but the Evolve is a very, very reliable machine. Hope this helps...
