Yarn Twists in Sewing Thread.
You cannot spin a yarn without the TWIST.
You can spin a yarn perhaps about 1/4 inch length by hand.
If you see cotton anywhere in your house take it and go to your room.Close all doors and open all windows.Sit facing a window,take the cotton in your hand and start pullin it slowly very slowly with your right hand while holding the left hand tuft firm with cotton.You will notice that they do not break but cling to each other with strands of fiber.Your right may have few fibers,now twist them with your thumb and fore finger it forms a thread of cirtain thickness.Do not stop the process but keep drawing and twisting to spin a yarn.How long you can spin the yarn and how fine you have spun it makes you a good spinner or just a learner.
How did you twist the yarn and what type of twist you did.As the fibers started coming from your left hand where you held the cotton tuft it was pulled by your right hand and you started twisting the strand of fibers in up word direction from your thumb to your fore finger,while the thumb did a clock wise rotation your fore finger rotated in the anticlock direction.You can do this with a wire and see the twist is a 'S' twist a right handed twist in the Shape if ' S '.
