After college, McGrew started building sand sculptures professionally. She has created artwork for festivals, concerts, and other events. In 2014, she worked on a record-setting sandcastle in Brazil. It towered more than 40 feet high!
To start a sculpture, McGrew builds a rectangular wooden frame, called a form. She fills it with sand mixed with water. Then she packs down the wet sand with her feet or a machine that pounds on the sand. Tightly packed sand holds its shape better.
McGrew stacks more sand-filled forms above the first one. Then she starts from the top and removes each frame one by one. This reveals a stack of molded sand blocks.
Next, McGrew sculpts the blocks with tools like shovels, spoons, and brushes. McGrew carves the basic shape of each part of the sculpture before adding details. It can take her many hours—even days—to complete a sculpture.
McGrew loves the feeling of satisfaction when she finishes a big project. But there is one annoying thing about the work. “I have sand everywhere—in my bags, in my computer, in my phone,” she says. “It’s not a job you can do if you don’t like sand!”
