The thread moves from the spool through the needle to make stitches on a sewing machine. The thread take-up lever is what feeds the thread from the spool to the needle as it moves up and down.
Throat take up lever
bobbin case
For the bobbin wheel. This is a small thread spool that is located below the sewing table. The needle draws out the bobbin and along with the top spool of thread, sews the garment.
The smaller thread feed at the bottom of the machine is called the bobbin.
Spool pins are used on sewing machines to hold the spool of thread. Most or vertical, some that are horizontal use a spool cap to secure the spool of thread. Some machine come with spool nets to cover the spool to ensure the thread enter the machine evenly. Some machines come with an extra spool pin that fits into a small hole on the top of the machine to hold a second spool of thread.
A spool of thread is very cheap. Spools of thread can be as cheap as a dollar or less a spool.
place spool of thread on spool pin
I don't think you can, I searched it and it said it took a knife, a needle, and a spool of thread.
the holder of a thread is called a spool
The thread must come from the FRONT of the upright spool on the back of the machine. Thread through the small eyelet on the back (nearest the spool(s), projecting from the top), then through the thread guide at the front of the machine. If you are using a double needle (therefore two spools of thread), the thread from the left-hand spool should go through the top hole and the thread from the right-hand spool through the bottom hole. Come down to the tension disks. Bring the thread through the back disk, up again under the wire guide, and down under the thread guide that is just to the left of the tension disks. Bring the thread through the eye of the take-up lever (the piece that moves up and down when you sew) from RIGHT to LEFT. Guide the thread back down through the thread guide next to the tensioner. There is a little thread guide just inside the door on the left side of the machine; bring the thread through this guide. Then pull the thread through the wire guide above the needle (it's easiest to hold the thread horizontally to do this). Thread the needle front to back. HTH. YMMV.
a spoolcase is something that you use in sewing or when you sew you put the spool into a spoolcase but you must make sure the spool is filled up with thread then you can start sewing only if you have a long piece of thread in the spool!!
A collective noun for thread is a spool of thread.
Shuttles are also called bobbins or loop-takers. This shuttle is a plastic or metal spool that holds the bottom thread in place so the needle can pick up the thread and create a stitch in the fabric.
