Once you’ve worked out which types of hardware are comfortable to use, it’ll be time to start thinking about shapes in relation to the shape of your cabinetry. In general, knob and pull styles should be matched to kitchen cabinet styles. What this means is if you have selected a plain cabinet style, for example, shaker or flat, ultra-modern doors, then you’ll want square, plain hardware to match — perhaps something like Emtek’s brass bar knob or a similar style. Recessed panel doors or doors with curving and intricate trim will often do well with more ornate hardware styles.
Sometimes brass finishes can be difficult to match since there are so many types (unlacquered, satin, antique, polished, etc.). Generally, you just have to order samples to see everything together. However, I will say that you should stay away from polished brass - it gives a very 80s vibe! Unlacquered brass starts shiny, but has a richer tone that gives a beautiful patina over time. For a more modern brass look, stick with the satin finishes!
