5. Start treadling, being careful to keep the thread smooth with no loops. If you can not wind the bobbin without leaving loose loops of thread, it means you can not treadle correctly. The bobbin should not be wound too full or it will not turn freely in the bobbin case.
Threading the Machine. - Although different makes of machines are threaded somewhat differently yet there is a general order for threading machines that is always to be followed. If you understand this general procedure in threading machines you can puzzle out how to thread any machine. Read the following directions and study Fig. 2 before you attempt to thread your machine.
1. Turn the hand wheel so that the needle is at the highest possible point.
2. Place the spool of thread on the spool pin.
3. Put the thread through the thread guide.
4. Draw the thread between the tension discs and through the loose guide if there is one. The tension is located differently on different types of machines. It may be on the front or on the side.
5. Put the thread through the take-up. This is the little lever that moves up and down.
6. Put the thread through the wire guide.
7. Put the thread through the eye of the needle from left to right.
After you have had a trial at the sewing machine you will find the following kind of practice to be helpful. Close your eyes and try to remember the exact order of steps in threading the sewing machine. Go through the motions of each step, moving your hands exactly as you would in manipulating the thread. This dummy practice will accustom your hands and arms to the larger motions.
Something to Do at Home. - 1. Try threading your machine at home to see if you can carry out these general directions.
2. Ask your mother if she has any bobbins she would like to have you wind for her.
The Lower Thread. - The bobbin which is to hold the lower thread should be put into a bobbin case or a shuttle. The end of the thread is drawn through the slit and notches in the bobbin case or shuttle. It is not easy to understand how this is done unless you see it demonstrated. Ask your teacher to demonstrate this so that you can see how to do it for yourself. Drawing Up the Lower Thread. - The next step is the same for all machines. The lower thread must be pulled up from below the table so that both the upper and lower thread can be pulled out behind the presser foot. The thread can be pulled up according to the following directions:
1. Turn the balance wheel so that it revolves once, making the needle go down and come up once.
2. Pull on the upper thread making the lower thread come up as in Fig. 3.
3. Catch hold of the loop and draw the thread out behind the presser foot.
4. Draw both threads back beneath the presser foot as shown in the second picture of Fig. 3. The upper thread should be drawn between the toes of the presser foot.
The lower thread must be drawn up before beginning to stitch, otherwise the beginning of the stitching will be knotted and tangled.
Speed Contest in Threading Machine Correctly. - 1. Arrange to work in pairs or in groups according to the number of machines and the number of girls in the class.
2. Have some one time you while you thread the machine.
No score for time should be counted unless the machine is threaded correctly. The threading is to include the upper thread, the bobbin thread and the pulling up of the lower thread.
3. After the time for each member of the class has been recorded, you can find out what was the shortest time required. It will be fun to try to beat this record and to improve on your own record. Starting to Stitch. - You will find it easier to begin your stitching on pieces of folded paper rather than on cloth. Be careful not to pull on the paper or cloth while you are stitching because it may break the needle. The cloth will move as fast as it should go. There are various things to be learned in stitching such as following a straight line, or a folded edge, turning corners, and finishing at the ends. There are some practice exercises on which you can learn these various things. Draw some straight lines on a folded paper and see if you can follow them exactly with the stitching. It will be better practice to have the paper four or five times as large as the diagram above.
After finishing a line of stitching and when removing the work from the machine be sure to stop with the needle at its highest point. Pull the threads back between the toes of the presser foot before breaking. This prevents the strain of bending the needle.
Fold the edge of a piece of paper like a hem and stitch the hem down, using the edge of the presser foot as a guide as shown in the diagram.
Draw some curved lines and try to follow them with the stitching.
Use a folded piece of cloth and practice turning square corners. This is done by leaving the needle down through the cloth, raising the presser foot, turning the cloth into the proper position, then lowering the presser foot again, and continuing to stitch. A square turn cannot be made unless the needle is left down through the cloth while the cloth is turned.
