OK, I want to build some cabinets that will extend from already in place cabinets and the wall. There is a face frame involved, so gaps can be filled. I will place the unit up as one cabinet, and I want them to go to the ceiling.
My question is: how do you guys deal with wavy walls and shimming when you can't reach over the cabinets? I want solid backs on the cabinets, so reaching through the front is not a current option. French cleats, but then I have to reduce the height of the cabinets in order to hang the cabinets. I'm a rooky, so looking for best options.
Thanks
