The soft texture of an infant's skin. The slither of a silk gown as it flows over the skin. The jagged invasion of a rock beneath one's body. Using touch when writing can bring a reader into the story. They may have felt the rough lips of a man seizing a kiss or the feel of hand clasping like vices. Toch can be used to bring many pictures into the reader's mind.
So use tough to give your characters depth. To make your settings come alive and in some cases to advance the plot. You can show a character's love, hate or fear using just touch. You can bring a setting into view by having the character touch the rough texture of the wall or the soft petals of a flower. Using the sense of tough can animate your story. So think of touch as you write.
