Is Red edged spread an example of assonance in a poem?

'Red Edged Spread' IS an example of assonance, although your typical examples tend to be constructed through a whole section, or stanza, of a certain work. In Paradise Lost, the author uses assonance in a different way, by using 'u' and 'oo' sounds frequently. If you read it slowly, it evokes a certain feeling in the reader's mind:

"...Hung on his shoulders like the Moon, whose Orb

Through Optic Glass the Tuscan Artist views

At ev'ning from the top of Fesole . . ."

I suppose the point I am trying to make is...that feeling is the key factor in using assonance in poetry, and it will take more than three Words to do that. BUT, red edged spread IS a simple form of assonance.
