Matching a texture is pretty tough. We usually skim the entire ceiling and re-teture.
I have a gift. people think i am full of it but i can make almost anything match. typcially alot of people should skim out the ceiling but that is very extreme. they usually like the cheap end and i can give that to them. so that is a plus.
OCD for tearing down a ceiling? I think not. I have been to many homes where that ceiling bugs the heck out of the HO because it dosent look perfect. You are not alone my friend.
