Knobs and pulls are kitchen jewelry that can dress cabinets up. Note that cabinet hardware can get very fancy and expensive — costing $30 and up for a single ornate knob. But you’ll get a huge bang for a few bucks by buying 10-packs of simple, contemporary hardware at big box stores for less than $20 (that’s $2 a knob!).
To save time and money, replace 1-hole hardware with 1-hole upgrades; 2-hole with 2-hole. That way, you won’t need to drill or patch.
