Your machine cannot do a cover stitch. Check the Brother website, they make a cover stitch only machine, it works much better than any of the serger/cover stitch combination machines, and it is a lot less money.

    Hi Tally Girl, I've been a sewing machine tech for 40 years. Your sewing machine technician is mostly correct; hiusehols coverstitch/serger machines are difficult to convert between serging and coverstitching, and they are a pain to keep working properly. Check out the Brother 2340CV coverstitch only machine, it is inexpensive, easy to use and never goes out of adjustment. You can buy one of them and a serger for less than a combination machine.

I read a great article on coverstiching yesterday in the Australian Stitches magazine - very interesting as the writer Martin said to use ELX (extra long) needles or SUX (ball point extra long) needles whenever doing coverstitch and don't use bargain thread cones - skipped stitches is a frequent complaint otherwise. He also recommended leaving a bit of hem turnup fabric exposed past the underside of the coverstitch as most knits will roll and you don't want it to roll where you are seaming. He said just trim it off afterwards with blunt nosed scissors.

I had been told previously by my sewing machine technician to leave all domestic coverstitch machines alone, they can all be pretty twitchy at times. He recommended an industrial coverstitch as changing a domestic between the coverstitch to hem then back to normal marrow seam is a fiddle. I find changing between rolled hem and normal seaming takes time too - would be nice to have two sergers.

FYI, a mock or faux coverhem stitch can be done, in conjunction with your sewing machine and the serger. Takes a bit longer than using an expensive coverhem machine but looks almost the same.

1. Make sure your hem is even and serge the edge using a 3-thread overlock stitch.
2. Iron a 1-inch hem. (Fold 1-inch to the back, wrong sides together) -- Measure to keep it even.
3. Using your sewing machine, you can get a double needle that will fit inside the zig zag hole of the needle plate -- if too large it will break -- and then thread both needles using two spools of thread and stitch on the right (top) side over the ridge that you can see that is from the overcast stitch -- it will be thicker to the touch. Slowly stitch all the way around. I start on the side seam and stitch over a couple of stitches to lock it. If you have ironed a neat hem, it will come out very nice.

If you have to use a single needle, then use a quilting guide bar attachment to follow the first row of stitching to get an even second row.

This can be done on sleeves and bottom hem. Stretch the material slightly to help avoid pulled and broken stitching when wearing.

You can't. it 3/4 sergers don't do the coverstitch.

I don't believe that the White speedylock 1600 does a coverstitch, however 3/4 thread sergers CAN do cover stitch. It's a misconception that you need five threads to do a coverstitch, for example, there are elna and janome machines on the market that coverstitch with only four threads.

How do I raise the feed dogs on the simplicity easy lock 880

The information I found on your machine indicates it is a serger. A serger's feed dogs should always be active unless your machine also has coverstitch capability. Perhaps you should look through your owner's manual. A sewing machine will sometimes have feed dogs that drop but, AFAIK, sergers don't do that.

Does the huskylock 530 do a cover stitch

If it is a serger and does not have the coverstitch conversion option, then no, it does not do coverstitch. (FWIW, the pictures seem to show a machine that was made several years ago before the combination machines were available.) Some machines are combination serger and coverstitch, but most users complain about the difficulty of converting back and forth between the two options. However, good used coverstitch-only machines can be purchased for a relatively good price compared to purchasing a combination unit.

Can you do a coverstitch on the Brother 634D serger

I don't think so, the D in your model name would denote that it has Differential feeding but is probably a 3/4 Marrowing stitch only. So this means it would do 3 thread overlock, 4 thread overlock and you can probably set it up for rolled hemming too.

Coverstitch is fairly new to home sergers and is available on some machines along with the 3 and 4 thread stitches, but changing between the regular overlock and a coverstitch takes a few minutes. The model number will usually have a "C" in the name. Also, during coverstitch the blades are disenaged and don't trim your fabric so you still need often to go back with blunt scissors and trim the raw edge.

And sewing coverstitch can be finicky, with skipped stitches a problem. Use high quality thread and XL (extra long) or SUX (stretch extra long) needles to avoid this.

However some manufacturers are now making dedicated coverstitch machines; if you are assembling a garment with your regular serger, you can then just move over to the coverstitch machine to sew the hems and necklines and not spend 20 mins changing over your machine's functions. Much more productive.

You may wish to check out the Brother 2340CV, this is their dedicated domestic coverstitch machine. Link to product info is

In the meantime, best solution is a twin needle to stitch the hem from the right side of the garment on your regular sewing machine, looks much the same, and you can get twin needles with a 4mm or 2.2 mm gap and in stretch and sharp tips for less than $10 each. Just iron up the hem about 1.5cm deep, and thread up your sewing machine with the twin needle and two spools of same colour on top (I just wind an extra bobbin and use this plus the original thread spool rather than buy two spools).

Just sew really slow as the twin needle builds up a lot of heat and will break if you push it along. I use this finish on all my knit garments and it works just fine. Sometimes I'll iron in a 2cm strip of fusible web inside the hem to give it some firmness in a neckline, then twin needle stitch at about 1.7 from the folded edge.

Hope this answers your question.

How to use double needle

That stitch is called a coverhem or a coverstitch. It is made with a coverhem machine which is basically a serger with an orbiting looper. Many upper end home sergers have coverstitch capabilities (Elna 945)

To use a double needle, simply thread two threads the same way that you would thread one. ONLY USE A STRAIGHT STITCH, AS THE NEEDLE WILL STRIKE THE PLATE IF IT ZIG ZAGS TOO WIDE.

MyLock 134D coverstitch?

While the ML134D is a very good entry level overlocker/serger, for coverstitch you will need a different or dedicated machine.
Janome has recently introduced a new model that is a combined Professional Coverstitch/Overlocker it is model 1200 D (Link) and is truly amazing in the diversity of stitch options
Their other coverstitch only machines are the CoverPro 900 & 1000
