Summarize this article:

Measure the length and width of the wall or surface that you are covering with stone. Multiply those numbers to find the square footage that you need to buy. Also measure the edges and corners, as these require different stones than the flat surface.  The majority of the area will be covered in flat stones. You may also want corner stones or edge stones. Flat stones are cut smooth on both ends to fit tightly together. Edge stones have a rough edge on one side for placement where they’ll be seen on the end of a wall. Airstone is sold in eight square foot packs of flat stones, six linear foot packs of corner stones, and seven and one half square foot packs of edge stones. AirStone adheres best with adhesive that is specifically designed for it. For interior walls, use AirStone Interior Adhesive. This comes in a bucket that covers 30 square feet of wall. Outdoor AirStone projects should use a tub of Loctite construction adhesive, which covers 10 square feet. If you prefer to use some other adhesive besides the one designed for AirStone, you are free to do so, but the result may not be what you want. Airstone currently offers three colors of stone, which are Autumn Mountain (tan), Birch Bluff (white), and Spring Creek (grey). These collections include stones in a range of colors, so be aware that every stone is not the exact same color. Since the stones in each color palette include a range of shades, you have a lot of flexibility to match them up with the other colors in the space. AirStone can currently only be purchased in the U.S. at Lowe’s, either online or in the store. AirStone, the manufacturer, does not sell their product directly to consumers. If you order online, you have the option to have your stone shipped in the mail, delivered by Lowe’s delivery service, or set aside for pick up at a local store.  Shipping costs may vary depending on how much stone you order and how far it has to ship. If you don’t like to order online, go to the nearest Lowe’s and pick out the stone you want.

Summary:
Calculate how much stone you need. Determine how much adhesive you need. Choose from the color palettes available. Buy AirStone from Lowe’s.
