I've installed my upper cabinets on one side of my kitchen. They are level, but I noticed when I got down to the other end from where I started, that I had a bigger gap between the top of the cabinets and the ceiling. Since my cabinets are level, I assumed the ceiling must not be, and sure enough, when I checked I found that it was not. I have 1 1/4 crown molding I was going to use and set the first cabinet so that this would install correctly. Now I find the gap on the other end is bigger than my molding, so if I fasten it to the top of the cabinets, I will have a gap between the molding and the ceiling. What can I do? I can't go to bigger molding as I have full overlay doors on the cabinets and have very little room to work with at the top of them.
