Cheap Reception Ideas

I am open to hearing and sharing cheap wedding reception ideas. For my centerpieces at the wedding I am opting for reasonable and useable items. I am going to Walmart or the dollar store to find beautiful and cheap unique vases. I have already bought random colored stones, and I am going to have Beta fish swimming at each table. Not sure but i might add bamboo or water lillies. Before the wedding i am setting it up with people to take the fish with them. I am tying mini bags of beta fish food to the neck of the vase with my colored ribbons. I am also considering Buying larger cheap vases to fill with oranges and lemons for a colorful addition to my summer wedding.. Happy Planning
