1) Only cut in the corners about an inch or 2 at most. You do want to roll the paint as close to the corner as you can w/o touching an adjoining, inside corner wall. 2) Cut lightly vs. heavily. A heavier cut will 'draw the eye' to the difference in paintings. 3) Consider painting IMMEDIATELY after cutting. This way, the paint get 'feathered'
If you can't fix the problem, don't worry about it. YOU'LL know it's there but your friends and family won't UNLESS you tell them. And if anyone says anything, tell them I said they have TOO much free time on their hands!
My best to ya and hope this helps.
