The sample is made on the front of the knitting. The loops are sampled as 3 groups. With the help of the right needle, the loop at the left end of the 3 loops is passed over the other 2 loops.

This process is called loop drop operation.

The 2 loops over which the loop is passed are knitted flat.

By wrapping our thread on the right needle and decreasing the loop, the decreased loop is increased.

On the back of the knitting, all the loops are knitted as purl knitting.

The finished Sieve Example.
