How do the blind interpret beauty?

Over the past weeks reading questions that elude to attractiveness and beauty it made me wonder how do the blind denote beauty? For the seeing beauty comes greatly from sight. Something that can be viewed. A sunset is beautiful because one can see the colors, the composition of the clouds, etc. The blind who have been blind from birth have never seen such, their whole world is experienced through smell, touch, feel, and hearing. Where a seeing person would see a bouquet of roses, and stop to admire its beauty. The sight can be faulty. If sight drew a person to the bouquet only to discover at close distance, the roses are silk and not real, the eye would not deceive a blind person. They would not know there were fake roses there because they could not smell them. With no visual cues to help, get in the way or distract, how does a blind person determine what is beautiful in things they cannot see?
