Poems can rhyme or be in a rhythmical composition of words. Poetry, by its very nature, makes demands on a writer who attempts to analyze it that other forms of literature do not.
Many couples find that they are at a loss of words when it comes to wording their wedding invitations. Find something that the both of you love or if you are creative, come up with your own poem to reflect your love. On most occasions, writing witty and tasteful romantic poems is considered to be tedious and better left up to the experts at Hallmark.
A poem should be written subtly and ensure it is not too emotional. Read other peoples love poems for inspiration and ideas, but remember, don't copy, the idea is to find your own angle on your relationship. Try to write a poem about how he or she is feeling about the relationship.
A lovely memento to keep over the years is a poem. What better opportunity could there be in life to appreciate the flowing beauty of poetic words than on a wedding day.
