This is a great gift thought for the bride who loves books and poetry, or the couple who's found more normally within a coffee shop then at a bar. Instead of obtaining an highly-priced bouquet of flowers which will wilt and die within a week, craft delicate paper flowers from his and her preferred poems and books to make a literary bouquet.
Not only will they cherish this present forever as an very thoughtful gesture, but they can normally take the paper flowers from the bouquet and place them within a shadowbox frame as a reminder of their shared taste inside the arts to hang in their residence together.
If they decide to still go with all the throwing of your bouquet, they will not only be passing on the superior luck of catching the "flowers", but spreading their literary taste at the same time.
This thought can operate similarly with music sheets for musicians or acrylic painted flowers for painters and so forth.
