Sand Sculpture is a versatile medium that allows you to create a sculpture measured in meters in the space of a week that could easily take a year in another medium. The process is so simple that sand sculptures can be constructed anywhere and allow passers by to be able to view the entire creative process and enjoy the result for months afterwards.
The surface of a sand sculpture is protected against the rain and wind, and the use of building sand makes the sculpture robust. If you are a festival then you may like a demonstration sand sculpture, or for something more impressive and robust; an exhibition sand sculpture. Have a go yourself with a sand sculpture workshop or corporate teambuilding activity. For something smaller and more affordable consider a tabletop sand sculpture.
Consider also sand drawings for the big day.
