Using a sanding block primarily serves to provide a flat surface for even sanding. This tool ensures that pressure is applied uniformly across the sandpaper, which helps in achieving a consistent finish on the workpiece. When a sanding block is utilized, it allows the user to control the sanding process better than using sandpaper alone, which can lead to uneven surfaces if not applied with care.

While the other options highlight specific uses of sanding, they do not encompass the fundamental purpose of a sanding block. For instance, while smoothing rough edges and preparing surfaces for painting are important tasks that might involve sanding blocks, they are ultimately functions derived from the need for that consistency and flatness in sanding. Creating decorative patterns may employ different techniques where a sanding block is not always necessary, making it less central to the primary use of the tool.
