Goiing to hopefully install my cabinets saturday. Does anyone have a good write up or just general good information and how to make this simple and turn out right. My floor is fairly level, not to many high spots. My buddy mentioned that you can take a 2x4 once you get a level line where you want ur upper cabinets bottoms to be and screw that on your level line then you can rest the cabinets on the 2x4. Ill info appriacated!
