The hem is the poem’s ending as an edge rather than a final lock. A strong hem may be a returning image, a shortened refrain, an understated statement, or a line whose sound settles without explaining everything. It prevents the poem from fraying into indefinite commentary, yet leaves enough loose thread for afterthought. In lyric poetry, the hem often echoes the opening with altered significance, showing that the poem has changed the material it first presented.

A hem is the poem’s finishing edge: its final line, punctuation, stanza shape, or return to an opening element. Like a sewn hem, it gives containment while leaving the reader aware that meanings continue beyond the page. A strong hem need not resolve every question; it may close the form while opening an afterimage. Compare the ending with the poem’s beginning and consider closure, coda, and aperture.
