| A sewing machine needs an
upper thread and a lower thread to create a stitch. A
stitch is formed each time
the needle goes up and down, at which point the upper and lower thread
connect and form a stitch. The lower thread area is where you will find
a bobbin. A bobbin can be plastic or metal depending upon your
sewing machine brand and type. A correct bobbin's thread should be wound
not too loose and not to tight. The photo above shows several bobbins that
are wound correctly. Many
problems with sewing machines are because the bobbin was either not
put in properly or not wound properly. If you have just purchased a
new sewing machine
you will find it comes with three or four extra bobbins. It is important
when buying new or extra bobbins that you purchase the same kind. There
are several different kinds of metal bobbins, so make sure you purchase
only the kind that can go in your machine. Your machine will break or the
stitching will not be proper, if you do not have the correct bobbin.
Once a bobbin is wound it needs to go into the
sewing machine. Some bobbins go in a separate case called the "bobbin
case", while other bobbin go directly into the machine which already has a
built in case for the bobbin. Do not
use old thread. I do try to save money here and there when I can in
sewing, but one place I do not, is in the area of thread. Old thread will
break easily. Make sure your thread is the correct kind of thread and make
sure it is new. |
