Here are some things to think about when you're hanging your kitchen cabinets. Start by hanging the upper cabinets first so the lower cabinets won't be in the way. Snap a level chalk line- along the wall to align the base cabinets. Then, establish a plumb line to make sure the top and bottom cabinets line up. Use shim shingles to help you level the base cabinets. Then, use drywall screws to secure your cabinets to the wall studs.
