I try and ride a fine line between plotting and pantsing. I like to have an outline of the major events and plot points, like character arrivals, character deaths, twists ext. I've learned not to go into fine detail, because when I start to actually put your pen to the paper, I notice a list of unforeseen issues because of the structure. So by not having a set in stone outline, I can move pieces around to make the story work better, and alleviate issues. But, I still have plot points that will happen, so I can foreshadow them even if I don't know exactly when I'll use them.
