There are a few options for hanging drawer hardware. Usually drawer pulls (or knobs or cup pulls) are centered on the face of the drawer. In a more modern kitchen, you may choose to hang them closer to the top of the face. For Shaker-style drawers, you can hang knobs or pulls either in the center of the drawer OR centered on the top stile. Which look should you go with? Whatever you like the best in your kitchen. Just make sure that you’re consistent across all the drawers. Drawers longer than two feet may look better with two knobs or pulls.
Let’s talk first about metals. As a general rule, I like to keep the different metals in a kitchen to no more than two. If you have stainless steel appliances, that counts as one metal. So that leaves one other metal you can bring into a kitchen. If you’ve got brass light fixtures, that’s your one other metal. Your new hardware should be nickel or brass.
