We had this cheapy wine rack from an old apartment, but the new house required an upgrade. This is all pine boards and 2x4s milled down at home, sans the the top surface inlay which is red oak. The inlay is a design element but is also the load-bearing square from the rest of the surface boards and attachment to the base. The center wine rack is 1/4" fiber board cut to size and pieced together with some clever geometry (though I think I'm going to save myself the grief in the future by making slots instead). The molding is custom made, it's milled furring strips and white boards ran through a few different router bits, cut on the table saw, then glued back together. The negative spaces on the doors and sides are filled with expandable steel grating cut to size with an cut away wheel, and then painted. The hardware for the rail and shelf mounts are store-bought.
