Basic steps for threading the bobbin

You want to start by familiarizing yourself with your machine. Most sewing machines have a similar layout for their functions and different parts.

If your machine has an automatic bobbin threader, it is usually in the top right corner of the machine. You will also want to know where the spool pin is on your machine, which is where your thread is on the machine.

Once you have your tools ready, here are the steps for threading a bobbin on a machine with an automatic bobbin threader:

  1. Place your spool of thread on the spool pin.
  2. Follow the instructions in your manual, pull the thread through the required areas to get it to the automatic bobbin thread threader. Your machine may have a guide, but many machines have a dotted or colored “ thread guide ” to show you how to get the thread from the spool pin to the bobbin winder / threader.
  3. Once you’ve pulled the thread through the correct parts of your machine, you’ll want to pull a little extra through it so you can thread your bobbin. Most standard spools have a small hole at the bottom or top of the spool. Pass your thread through the hole, pull a 2-3 inch thread through the hole.
  4. If I threaded your bobbin, check that it still attached your thread to its thread guide and place the bobbin on the sewing machine winder. Make sure the thread end is sticking up out of the bobbin and not down towards the machine.

Often you will have no problem sewing on a project, but then the thread will get caught or wrapped around the bobbin wrapped.

Even though it looks like the bobbin is causing the problem, there may be some other culprit lurking in your sewing machine. The tension in the upper thread may not be correct, so you can retread your machine to make sure it holds the correct tension.

If you still have problems after that, there are two other things that can cause bobbing to bunch up: the wrong thread or the wrong needle type. Make sure your bobbin thread matches the top thread and that you are using the correct size / needle type for the fabric you are sewing on.
