I found some neat Wedding favor bags that have little trinkets and some bird seed in it for the guests. People don’t use rice anymore because the birds eat it and it swells in their stomachs, which is bad for them. So now we use bird seed and it serves two purposes. Keeps the birds safe while allowing the tradition of throwing seed or rice for plentiful crops or fertility to continue.
I have always liked that tradition as it is so fun and signals the start of a new life for the bride of groom. It has a lot of romanticism and practicality within it.
