Guide the Thread
Thread the Bobbin
To thread the bobbin, you will need to find the bobbin winder. This is usually located on the top of the sewing machine. Place the bobbin on the bobbin winder and thread the thread through the tension disc. Wind the thread onto the bobbin until it is full. Then, remove the bobbin from the bobbin winder and cut the thread.
Insert the Bobbin Casing
To insert the bobbin casing, you will need to open the bobbin door. This is usually located on the front of the sewing machine. Place the bobbin casing into the bobbin door and close the door.
Draw up the Bobbin Thread
To draw up the bobbin thread, you will need to hold the end of the thread and turn the handwheel towards you. This will draw the thread up through the bobbin casing and into the needle.
Thread the Needle
To thread the needle, you will need to insert the thread into the eye of the needle. You can use a needle threader to make this easier. Once the thread is through the eye of the needle, pull it through until there is about 6 inches of thread left.
Thread Tension
The thread tension controls how tightly the stitches are sewn. To adjust the thread tension, you will need to turn the tension dial. The higher the number, the tighter the stitches will be. The lower the number, the looser the stitches will be.
| Thread Tension | Stitch Tightness |
|—|—|
| 0 | Loose |
| 5 | Medium |
| 10 | Tight |
Thread the Needle
Threading the needle correctly is essential for proper machine stitching. Here’s a detailed guide to help you thread the needle:
