Sequence of Single thread Chain Stitch Formation

Red thread = Needle Thread

Fig 1: the needle is at the top most position and looper is holding the old loop.

Fig 2: the needle penetrates the fabric and Looper starts to move back.

Fig 3: the needle reaches the lowest position. The looper reaches the back most position thus releasing       ……….the old loop.

Fig 4: needle starts to move up and looper starts to move forward.

Fig 5: the looper catches the new loop.

Fig 6: the needle moves to the top most position and thus a chain stitch loop is formed.
