Sewing with knits can be extremely satisfying but it can make a big difference between your apparel that obviously looks handmade and is finished professionally if you are able to thread and then use it correctly. I will walk through you in this post to reach a double needle helm so that you can feel confident about the recent explosion of the cutting patterns.
What is a Double Needle and Why use one?
Also known as a twin needle, two needles are attached to a single needle, hence the name double needle. One of them is less than the other so that the bobbin can pick up the thread from both needles. It can help to create the topstitching by imitating the neat double stitching row commonly observed in the shop-bought knit garments ‘ jacks, slippers, and necklines. Many machines can operate with a double needle, but first, check your threading guidelines in your handbook.
Choosing the right double needle
Double needles are available in different sizes just as regular needles are available— two numbers highlight the distance between the needles and the size of the needles. Double needles are available in various sizes. The 4/90 double needle has a distance of 4 mm, for example, between the size 90 of the needles.
If your manual does not give your machine a preferred size, ensure that the distance between your needles is not bigger than the widest size of your machine so that the throat and bobbin case cannot be damaged. To confirm this, you can use the widest zigzag and shortest stitch long to run a piece of paper through your machine (with no thread).
Pre-requisites for using a double needle
You may not be able to use a double needle on all sewing engines. Pre-requirements for use of double needles You can use a double needle when your sewing machine at least supports zig zag.
When a double needle is used, try searching the threading instructions manual to find out what the double needle size fits into your sewing machine.
A four-twin needle size means the needle gap is four mm between the two eyes. The best way to learn this is if there is no information on the size of the manual.
Run a piece of garbage or paper threadless. The largest distance is right for you. Transport the paper to the store if necessary and purchase the proper size.
Threaded threads You need two thread spools. They don’t have to be of the very same color unless you really want it.
You can load the bobbing and use it as one of the spools if you are not interested in purchasing two threads of the same color and still want to use the same color.
It’s easy to load the bobbin. Use a stick that doesn’t hold the spool so firmly. Hold the thread end and hold the stick with one hand. Run the bobbin sewing machine and roll the thread.
Make sure that the double needle passes through the base plate. If you don’t have the correct foot plate with sufficient opening to allow both the needles, you need to use the zig-zag presser foot carefully.
The zig-zag press foot has a wide mouth that allows the double needle to move around easily.
With these, you are prepared to spin the wheel and create a double stitch that looks like a store dress.
HOW to THREAD A DOUBLE NEEDLE
Step 1: Replace the usual needle with the twin needle, exactly as your needle is usually altered.
Step 2: Thread the left needle as you’d use your regular upper thread to thread a regular needle.
Step 3: Place the additional spool pin on the winding shaft and top with the second thread or spool. You can always just drag that near just use one of its spools if your machine does not come with an extra spool pin and you’ve got an overlock. Or, both spools can even be placed where your single thread spool would be.
Step 4: Thread your thread with the right needle. Once again, you would thread it in the same manner as a normal needle, but do not cross the thread this time.
Alternatively, you can pick up the two thread ends and wrap them through your machine just as if it were one thread.
Step 5: Go ahead and sew on the right side of your fabric. My machine is happy with both a zigzag and a straight point, but bear in mind that with some you can use only a straight stitch, but with others, you can use a number of decorative stitches.
I have used the length and tension of a steady stitch for the medium weight jerseys, but tension and foot adjustments can be necessary for various weights and types of knit fabric.
