 With trim, it's a little easier depending on how handy you are. With trim, what you do is you would just go to a piece of trim in the room that you'd like to match it to. You'd score, which basically means you take a utility knife or a putty knife and you'd break up the edges where that piece of trim meets the wall and meets the other areas of trim because typically it's caulked in place and you can't just go popping it off because you'll probably rip off the wall and the other trim that's associated with it and maybe some paint.
