What is a Bobbin in Sewing?

bobbin is an essentially small metal or plastic wheel and circular shape component at which the thread is spun around enabling it to work on the sewing machine.

Moreover, a small cylinder is mainly attached to the bobbin’s thin wheels and this is where the thread is wrapped around.

The bobbin is an important part of the sewing machine which is mainly a small wood or plastic, or metal wheel comprised of reel design that holds the thread.

It has a designated space on the cylinder where the thread is spun around perfectly.

Then thread from the bobbin passes through the plate and connects with the top thread forming a tough stitch while using the sewing machine.

It is paced at the lower side of the sewing machine, and the machine makes a stitch by catching the bottom thread, from the bobbin, with the top thread, from the needle.

Common examples of bobbins are spools and cylinders holding yarn, wire, or string. Even in weavers and knitters’ bobbins are used.  

It is suggested to have more than one bobbin and choose the right kind of bobbin for your sewing machine according to the model.

Just be aware not to leave the tail of your thread sticking up as it can disrupt the connection of the top thread with your bobbin.

Never try to overfill or bulge plastic bobbins i.e., wind the thread in an even manner (requires little practice).

Also, avoid loose threads on the bobbin, it should be done properly and spun in the right direction for accurate sewing.

Bobbin’s usage is to feed the thread through the machine, offering a series of stitches that are secured.

It’s suggested to only bobbins that are specific to the same class/style as those that come with your machine.

You must avoid any new kind of bobbin substitute. 

Difference Between a Bobbin vs. Spool

Bobbin: in a sewing machine, it is a wheel-like component that mainly holds the lower thread.

Therefore, a stitch is created by looping the bobbin thread and the needle thread together.

Spool: The spool is what holds your thread spool, it can be vertical or horizontal.

A spool holder/cap is a little stopper that secures the spool in place. Without the holder, the thread spool would be shaken while sewing.

A spool usually holds a thread at some point on the top or side of a machine.
