Guidelines: Writing the Sonnet

It must be quiet:
heart's I am, I am
like a faint purred thrum
of insect wing hit
against draped pane. Let
each own its rhythm,
but privately, slim
breath that's kept discreet.
Try to picture it
as a slattern hemmed
in by a corset,
tempered by wisdom,
mulling a solemn
dress of green velvet.
