Datum planes are useful to support the sketches. These auxiliary planes can be based on the Origin of the Body, or can be based on the features (edges, faces) of previously created solids. In addition, a PartDesign ShapeBinder can be used to import external geometry into the body to serve as reference; then sketches can be attached to this auxiliary body, either using datum planes or not. Using datum objects is often the best way to produce stable models, although it requires a bit more work from the user.
