Mandy started the assembly. Krista and Kim helped as well, so that when I got home, we could start hanging them.
The cabinets hang on metal rails screwed into the walls. I used my handy dandy laser level to ensure that all of the rails were, well, level.
I had some good help putting the cabinets together. After hanging the cabinets on the wall, I screwed the faces of them together so that they would be perfectly flush.
We installed the cabinets around the fridge and almost all of the other cabinets. We ended up being five base cabinets short, due to a mis-delivery by Ikea/Budget/Best Buy. The missing bases showed up a week later, and are now installed.
Nate came over and helped lay out the island.
