This stitch follows a zig zag pattern. It can follow easy curves and can be used creatively to create fillings.

I will work this stitch between two parallel stitch lines.

Fig 1: Bring the needle through A. Take the needle in through B, a point diagonal to A. Now, come out through C and go in through D, as shown. B would lie between C and D. Come out from B.   

Fig 2: Now, go in through E, out from F and in through G as shown. E lies in the middle of F and G. Come back out through E. 

Continue with this process.
