Everything you ever wanted to know about quilting with a twin needle

 

In this five part series we’ll explore some of the different ways that you can use a SCHMETZ twin or double needle for quilting on your home sewing machine.

The possibilities are endless so let’s have a little fun!

What is a twin needle and how do I use it on my home sewing machine?

A twin needle, also known as a double needle, is a single shank with two needles attached. It’s used to make two parallel rows of simultaneous stitches.

This needle is attached to your home sewing machine the same way as a regular sewing needle.
You must have a zigzag sewing machine as opposed to a straight stitch only machine.

This is because a straight stitch machine does not have a large enough opening in the needle plate to allow the twin needle to pass through.

The needle package gives you important information

The top of my package says SCHMETZ. This is the name of the company that makes the needles I’m using. Top quality needles allow your machine to make the best possible stitch.
I know I can depend on SCHMETZ needles to give me beautiful results.

The second piece of information the package tells me is that I have a Twin Needle.
Under the words Twin Needle it says 130/705H-J ZWI. This is just a code that means that it has a flat back home sewing machine needle with a scarf (little notch) just above the eye of the needle.

J means it’s a jeans needle and ZWI means it’s a twin needle.

The most important pieces of information are what comes next.

This package has the words Jeans Denim easily confirming the information given in short form.
Twin needles have the same properties as their single siblings so we know that a jeans twin will have a nice sharp point to easily pierce all of our layers of fabric and batting.

The numbers at the bottom of the package tell you the space between the two needles and the size of the needles.

On the left is the distance between the two needles. In this case 4.0. The larger the number the larger the space.

On the right is the size of the needle. Once again, the larger the number the larger the needle.
This one is a size 100 so it’s quite thick and has a large eye.
These properties make it a good choice for quilting as it won’t bend too easily and the
large eye can easily accommodate 50 weight cotton or heavier thread.

Twin needles are available in a variety of types and sizes. For our twin needle quilting we’ll use the Universal, Embroidery, Jeans and Metallic needles. These range in size from 1.6/70 all the way up to 8.0/100 with the Universal category having the most options to choose from.

The size of the opening in the zigzag plate of your sewing machine will determine the maximum distance between the two needles that you can use.

TIP To determine the widest distance between needles that you can use check your machines zigzag settings.
If your widest stitch is a 5 then your widest twin needle will be a 4.
If your widest zigzag is 7 then your widest twin needle will be a 6.
If your widest zigzag is 9 then you can use the largest twin needle of 8.

Threading your machine

Using a twin needle requires two spools of thread on the top and a single bobbin below.
The two top threads are both caught and held in place by the single bobbin thread. This gives the stitch on the bottom the look of a false zigzag. We’ll explore this in detail on day four this week.

It’s possible to wind a bobbin and use it for your extra top thread if you don’t have two spools.

 

It is not always practical to purchase two spools of thread for your twin needle stitching. You can replace one of the top spools with a bobbin wound with your chosen thread.
A bobbin can be used in place of a second spool of thread

 

Wind a bobbin with the same weight and type of thread as you’ll be using on the top. I’ll be using 50 weight cotton in the top and bobbin.

If you’re using small spools of thread you’ll sometimes be able to put both spools onto one spool holder.

When using two larger spools of thread you’ll need to use two separate spool holders. Most machines have this capability.

 

Two small spools of thread can be fed through the machine off a single spool pin. SCHMETZ

If your machine doesn’t have two spool pins or if the spool pins are too small to allow your thread to feed smoothly then an upright cone thread holder is an ideal tool.

 

Upright free standing cone thread holders such as this one made by UNIQUE Sewing and available at your local quilt store. It's an excellent if not essential tool, especially if your machine does not have two spool holders. How to thread SCHMETZ twin needle.

Thread both threads through the normal pathway.

First thread the left needle from the standard spool pin. This will be the one closest to the left side of your sewing machine. Once again, follow the normal pathway and thread the right needle from the secondary spool pin. Threading the needles one at a time will keep them from twisting together.

Thread the needles one at a time being careful not to let them twist. SCHMETZ

If the threads seem to want to tangle then put the one on the right through the last thread guide and the one on the left in front of the last guide.

Remember Don’t use the needle threader on your machine to thread a twin needle. You could jam the needle threader and cause damage to the machine. If you have an automatic needle threader consider putting a sticky note over the activation button as a reminder not to push it! Place your bobbin in the machine and bring up the bobbin thread.

Most times it's best to skip the last thread guide with the left needle thread to prevent tangling. All about SCHMETZ twin needle

Some computerized sewing machines have an internal setting that you activate to tell the machine what twin needle you have on the machine. Using this setting will give you optimum stitch quality as it helps control the thread tension. It’ll also prevent you from selecting a stitch that’s too wide for the twin needle you have on the machine.
