Wet Sand
Different kinds of sand have different saturation points, or capacities for absorbing water. All the sculptor needs to remember is that the sand needs to be very, very wet. Any excess water will just dribble away, so it's better to err on the side of too much water than too little. Sand that is too dry will not stick together, and is difficult to sculpt into the desired shapes.
Tools
There are a wide variety of possible tools ranging from specialist sand sculpture equipment to simple household objects. Sand sculptors should make sure they have an implement for carving the finer details. This can just be a small spade or sea shell, but the ambitious builder can go online and purchase a tool kit. Shapers vary in size, but are similar to palette knives with a flat head and a handle. In addition, a simple drinking straw can be very useful for blowing away excess sand granules once the sculpture is complete.
Dribbling
Making a sand sludge with lots of seawater and then pouring this mixture over the rough outline of the structure can create an interesting melted effect. This can still be sculpted afterwards, and a combination of sculpted and melted detail makes for a very unusual piece of sand art.
Location
It's a good idea to build a sand sculpture fairly close to waterline as it will be necessary to make repeated trips to fetch water and wet sand. Of course, builders should also make sure that the sand sculpture is far enough away from onrushing waves that the sculpture won't be destroyed.
Pack the Sand
To make a sand sculpture, it is essential to start with a large pile of sand. The pile should be the same height and width as the eventual finished piece. Most importantly this pile needs to be tightly packed, so make sure that each new bucketful of sand is pressed firmly into the mound.
Work From the Top Down
To avoid ruining details further down the sand sculpture, make sure to work from the top down and ensure that every detail is finished before moving down the structure. Carving details into the sand will inevitably dislodge sand onto areas below.
