I am creating a map layer of my three states:Indiana, Ohio and Kentucky with the zip code polygons around them. However, there is not really a clear outline and because of the shape of the states (Kentucky and Indiana are not exactly pretty polygon-shapes). I could edit them, but I feel like that would be hard to follow the outline of Kentucky and Indiana, especially with them not being exactly pretty shapes. Besides editing I have tried playing with in in the selection options, to no avail. Can someone help me make the states outlines look clean, clear and crisp?
