Dharker uses a clear lack of rhyme scheme to create a more free-flowing text, with fewer steadfast rules.
This creates an impression of freedom, perhaps showing how human attempts to exert control are futile and rather there should be freedom for expression and dissent.
The lack of rhyme heightens her message of the importance of freedom.
Unlike other poems which often focus on an experience or a character, Tissue instead explores a key idea free from the constraints of a singular experience or historical event.
Perhaps Dharker opts for the lack of rhyme scheme once more to show the importance of freedom as well as allowing her to explore her idea more thoroughly.
This method is used to potentially analyse her sentiment on a level above time and humanity.
