I am in the process of building a set of built in base cabinets that will perform the dual function of storage and a workspace for my wife’s sewing. I am making the base cabinets out of birch plywood and will have poplar face frames. I am looking for opinions on what type of material should I use for the countertop. My first thought was that I would use a single ply of 3/4” MDF with a poplar edging, but I am open for suggestions. I intend to paint the entire cabinet white. Also, what recommendations do you have for finishing these cabinets (materials & techniques), I do not have experience painting cabinets and am looking for a quality finish but it doesn’t have to be furniture grade by any means. My patience wears thin when it comes to painting so the simpler the better.
