Need advice regarding painting.

[Laurian]

We have lived in our house for 20 years and the bedrooms still have the original paint from when the house was built. Now that I'm retired, I've decided that I will paint each of them with a goal of finishing the four rooms by early fall. (I'm finding the job to be more physically demanding than I expected, so I paint one day and then take several days off.) I've mostly finished the first room. I'm happy with the color and the results EXCEPT where the walls meet the ceiling. It is uneven in some places. I taped it off before starting because I know my hand is not very steady. I'm thinking the walls may be a little uneven but it was not noticeable before because the wall color and the ceiling color were vey similar.

I'm thinking I need to carefully re-tape and paint the top of the walls again to try to correct the problem. Oh, but I dread doing that. My husband says nobody will notice, but I notice and it will drive me crazy the way it is now.

Any experienced painters here with a solution to my problem? I'd like to figure this out before I start on the second room.

Thanks!
