I have created a custom overlay Township Range grid for an atlas. My graticule labels lat long on outside of data frame and the custom overlay grid labels TWN RNG on inside of data frame. See Attachment. I have a feature class in the main data frame that labels town range with a font and halo. Custom Label Expressions are not functional yet in custom overlay grids. I want to make the custom overlay grid label have a halo just like the feature class is labelled in green with the white halo. I have thought of making a custom font with a halo but have never tried this. Thanks for any thoughts and suggestions.
