Using a circle of stone
A round gravel area is easy to lay out with a stake and string at the center. Set flexible edging along the line and lay fabric inside before the stone goes in. For a fire pit area, keep combustibles well away and check local burn rules.

Buying the stone
If you haul it yourself, a typical half-ton pickup should carry only about half a cubic yard of stone, well under what the bed looks like it can hold. Decomposed granite packs into a firm, natural path when wetted and compacted in thin lifts. Ask your supplier for their own tons-per-yard number, since stone source and moisture change it.
Common mistakes
People often forget that compaction reduces volume, so they come up short. Others order clean, round stone where a packable crushed stone with fines would have stayed put. Finally, dumping the whole load in one pile far from the work area adds hours of wheelbarrow trips.
Planning the cost
Stone is usually priced per ton or per cubic yard, and delivery is often a separate charge based on distance. A full truckload can cost less per ton than a partial one, so it can pay to combine projects. Ask whether the quote includes tax, delivery and any small-load fee before you compare yards.
