Why do sewing machines have two threads?

How does stitching work? Sewing machines have two threads because the needle pricks fabrics, lets the first thread through, and makes a knot with the second thread. This is how sewing machines have been creating stitches. When you use your hand, you have to push the needle you have threaded through a fabric.

How can you thread a sewing machine?

Threading a sewing machine can seem challenging at first. However, after you master the steps stated above, you will find it becoming a habit.

1. Set bobbin fully threaded:

How a bobbin works? The bobbin is the lowest spool of the thread. If you do not have bobbins wound with the thread already, you must wind from the spool of thread.

Keep sewing thread on the thread pin. The thread pin lies on top of the sewing machine. Pull the thread to the left side and wind it across the pre-tension disc in a counter-clockwise direction.

Thread the threads through two holes in the empty bobbin. Wind the thread a couple of times around the center of the bobbin. After placing the bobbin on the winder pin, and then press the foot pedal.

2. Spool pin:

To set the upper thread for the sewing machine, please place a spool of thread on the thread pin. Pull the thread into a groove on the front of the sewing machine. Bring the thread back in the second groove lying on the left.

3. Feed through take up lever:

Wrap the threads around the take-up lever. The take-up lever is a metal hook lying on top of the sewing machine’s second groove.

4. Rotate handwheel:

Pull the thread down towards the needle. For upper and lower threading of sewing machine, thread the needle from the front to back. Continue pulling the thread until several inches of thread goes through the needle.

How do you thread a bobbin?

Threading a bobbin is perhaps the most difficult part of using sewing machines. Implement the below steps as cautiously as possible –

  • Start with a thread and an empty bobbin
  • Pass the thread into bobbin winder
  • Keep the thread secured
  • Insert bobbin into the winder shaft
  • Keep the bobbin secured
  • Start winding
  • Make sure the bobbin is wound tightly
  • Load the bobbin into the case

If you find the steps a bit confusing, please go through the instruction manual. The sewing machine manual contains diagrams that show the correct way to thread specific bobbins. The manual will also inform you which model to select when buying the replacement bobbins.

Why does my sewing machine keep breaking thread?

Your sewing machine will break threads when the machine is not threaded properly. The thread undergoes immense tension and creates knots. There are other factors at play as well –

  • The thread tension is very tight
  • The needle temperature is too high
  • The thread is thicker for the needle
  • The needle is inserted incorrectly
  • The needle is ruined

Why does the thread bunch up on my sewing machine?

The thread bunches up on the sewing machine when the thread tails coming out of the bobbin are two inches shorter. They get sucked into the machine when sewing. Start with three-to-four-inch-long thread tails or hold the thread tails in position until you have made a few stitches. This is specifically important when you are sewing using knit fabric.

The thread bunches up if lint accumulates in the bobbin case. The lint may get in the way of the needle and prevent the hook from creating stitches. Clean the sewing machine to make sure you do not get bunched up thread beneath the fabric.

Other reasons include –

  • The sewing machine is not corrected in the right way
  • The thread tension is extremely tight
  • The feed dogs are down
  • The pressure foot is up
  • The spool cap is either not secure or missing
  • The bobbin is not inserted properly

Why does the thread keep coming out of my sewing machine?

The thread continues coming out of the sewing machine because maybe you did not pull out lots of thread. Please pull about 10 cm to 15 cm thread from both the bobbin and upper thread before pressing the pedal.

Even if you have a long thread tail, you may experience unthreading when you fail to keep the needle at its highest position. If the needle is in a low or medium position, the thread will unfortunately pull out.

Can you use regular thread in a sewing machine?

If you plan on lower threading, you should pay attention to the thread you are using. Can you use regular thread in a sewing machine? That’s a query most people have.

Although all-purpose polyester threads work wonders on most materials, in case you are working with a different type of fabric, one that is heavyweight or stretched, you must use the same kind of thread as the fabric. Suppose you are sewing a 100% cotton material; you must use a 100% cotton thread. The thread’s weight should also match that of the fabric.

At times, sewing instructions and patterns also inform you on the kind of thread you must use. If you cannot find the exact color, please go for a thread that is at least a shade or two darker than the fabric. A light-colored thread will stand out. Anyway, make sure to purchase a high-quality thread.

What is the best thread for a sewing machine?

how does a sewing machine work

Cotton and polyester threads are generally used in sewing machines. Depending on your project, either one can be a better option. If you are using the machine at the highest speed, cotton thread will easily endure the heat and friction better than polyester thread. Polyester is the best choice if you make clothes as polyester thread has stretch.
