The cons are a few: 1. MDF is heavy in relation to wood or plywood. 2. MDF does not accept screws very well. You must use coarse thread screws and always pre-drill. Apply the hinge screws by using a hand-held screwdriver instead of a screw gun. If you don't, they can strip the hole quickly. 3. Over time the screws will come lose just from opening and closing the doors (just go around every so often and tighten the screws). 4. If water gets into the doors, they will swell and they will need to be replaced so seal them well.
It’s important to choose hardware that will complement the rest of your kitchen décor and accentuate its worthy features. Generally, most people want their cabinet and drawer hardware to coordinate with the handles on their appliances. The colors should work well together, and the finishes shouldn’t clash. Drastically different shapes can also make your kitchen feel cluttered. You should use functionality and your personal preference to approach choosing knobs vs. pulls, but there are a few general guidelines to follow that correlate with your style of cabinets.
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.
