Most of the time you can shim the cabinets as you go, but if there's an extreme bow in the wall
(more than 3/8 in.), shim it out before you hang the cabinet. If you don't, you may accidentally
pull the back off the cabinet while fastening it into place. Hold a level across the wall, and slide a
shim up from the bottom (go in from the top when you're doing the top side) until it's snug. Then
pin or tape it into place.
It's easier to hang the uppers when you're not hanging way over the base cabinets. Rest the uppers
on a ledger board — it'll ensure a nice, straight alignment and eliminate the frustration of holding
the cabinets in place while screwing them to the wall.
