One thing you should get right with sewing machines is threading your bobbin the right way. The bobbin is one of the parts of the sewing machine that should not be overlooked. The bobbin is usually that small metal, wood, or plastic wheel in a reel design. What the bobbin does is hold the thread for sewing. It has a space on its cylinder that allows you to wrap the thread around it. You can choose to thread your bobbin with a winder mechanism, but most people prefer to do it with their hands. You can easily detach it and wind the thread by yourself. You should know how to thread a bobbin because it’s a critical part of the sewing process. You can’t use the sewing machine without it. It is what allows the machine to create a stitch. You will learn from this article, how to thread this multipurpose piece of equipment with ease.

Do all sewing machines thread the same way?

How to Thread a BobbinSome people make the mistake of thinking that bobbins are universal and can be used for all types of sewing machines. The bobbin area has to match the bobbin it uses. If it isn’t a match, it will cause problems with your sewing. For instance, you have a sewing machine that uses a plastic bobbin; its tension value will be different from those that use metal bobbins. If you use the wrong bobbin, it will make the tension lose its balance, and you will get a bad stitch. You must use only bobbins prescribed by the sewing machine manufacturer if you want a perfect stitch when you sew.

However, the good thing with some machines is that the bobbin systems have a top loading design like you can find in many Janome sewing machines. This makes the bobbin easy to load for beginners. One of the machines with the most easy to load bobbins is the Janome 4120QDC, according to consumers, thanks to the easy to load jam-proof bobbin system. However, some models have the extra functionality of running the bobbin winder, without the sewing machine running. This is thanks to the automatic bobbin winding clutch, as can be found in the Singer Quantum Stylist 9966 machine.

Asides the bobbin loading design of the machine, it’s also helpful if the machine has a system that helps you manage the thread automatically. For this, while choosing the best sewing machine to use, ensure the machine includes the Drop & Sew™ Bobbin System technology.
