Nowadays most couples spend thousands on venue rental for small and large weddings. Consider having your wedding at home indoors or in the garden. The option of an outdoor wedding sounds amazing but always have a back up plan incase if weather upsets such as rain.
Your home could be decorated to match your wedding theme or colours. You could always consider renting a rent or small marquee tent for the garden to add that extra touch of elegance.
Thus option aids to keeping costs down.
