Let's start knitting by pulling 12 chains. Let's create three squares 4 by pulling the chain occasionally. Let's continue with the boxes until our shawl is the length we want.

Let's start with the boxes on the shore to create the first frill. Till each box is filled, take as many loops as possible from the edges of the boxes and stretch them to the ruler.

Fill the inside of each box until it is tight.

Remove the ruler when it is full. Complete a whole shore in this way.

When the boxes are finished filling, connect each entangled extended chain one by one with the extension next to it. As the joining process is done, a frill will form.
