Party Favors

My high school buddy and his girlfriend are planning to get married next year. They are on the process of saving money for their wedding. He told me that he wanted to give his girlfriend a decent wedding. I wonder what wedding gift or help I could offer to grant his decent wedding for his girlfriend. As I look over the internet, I found interesting wedding favors that would complete an ideal decent wedding. Their wedding guests will absolutely like it because it is unique and beautiful.
