How To Minimize Appearance of Paint Line Buildup?

Good Questions

Q: I'm in the process of repainting my daughter's room. It is currently painted two colors, and I noticed that there is a distinct line between the two. I have a feeling that if I paint over the line, it will be very visible. How would you suggest I remove the line before painting the wall one color? Thanks for your advice!
