I love the idea of the elopment announcement and the running shoes!!

Whats the cost of the chair covers? If its expensive and the chairs are fairly decent, then you dont have to have the covers, you could use that money towards drinks. Also - ask if you can bring your own table decorations - that way you could get some larger candles, tea lights and other bits and pieces along the table, for around $20 - $40 and spruce things up that way. (Id go to those $2 shops).
