In the market for new kitchen cabinets? You really can’t tell a cabinet by its cover. No matter how attractive the outside, it’s what’s inside your cabinet that really counts. The best-quality interiors are made from ¾-inch hardwood plywood. Door and drawer construction is also important. Get a good look at their joinery and test out the glides. The care and workmanship will be clear in these details — so get a handle on them before you buy.
