Can a bobbin be upside down?
Bobbin work amounts to sewing upside down where the decorative thread goes in the bobbin, and you sew from the wrong side. The embellishment thread doesn’t need to go through the needle.
A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.
Why does my zig zag stitch look weird?
Your zig-zag stitch might look straight when the upper thread appears a single line. It usually happens because the lower thread is incorrectly threaded. Instead of applying the correct tension to the lower thread, you pull it through your fabric when you pull the upper thread.
Locate your reverse stitch knob, button or switch. Reverse stitch mechanisms are most often located on the front of your machine, either on the center of the faceplate, above the needle or on the left-most front.
Where is the reverse switch on a Singer sewing machine?
Press the reverse button, which is the button that looks like a “U” with an arrow attached to it. Most Singer machines have this button on the face of the sewing machine; it’s referred to as the “back-stitch” button.
Why does my sewing machine keep jamming underneath?
However certain you are that the problem with the machine is most likely due to a huge tangled mess of thread in the bobbin underneath the fabric, the most common reason for the jamming is usually the lack of sufficient tension in the upper thread.
Can I use metal bobbins instead of plastic?
Can I interchange metal and plastic bobbins if they are the same size? Metal bobbins and plastic bobbins of the same size can NOT be swapped. Machines are set for a very precise tension setting. If they are set for a lighter plastic bobbin, the tension will change if a heavier metal bobbin is used.
How do I know if I need a new bobbin case?
A quarter of a turn is a lot. Again, you only need to worry about the bobbin tension if the factory set bobbin tension isn’t creating a balanced stitch. As long as you take good care of your bobbin case, it will perform well. However, eventually, it will cease to sew smoothly and will need to be replaced.
What is the difference between Class 15 and 15J bobbins?
They look almost identical, but class 15 bobbins have flat ends, while class 15J bobbins have slightly curved ends. Sometimes they appear to work interchangeably, but even if they fit into your sewing machine, there is a risk of them jamming your machine up and causing major damage.
