I need to make boxed for several different stones, and was planing on doing a simple frame and panel construction maybe with some decorative veneer in the top panel. I decided just to look it up just now and it seems 99% of boxes I can find online are made from two solid pieces. both are simply enough, but I was just wondering if there is any issue with wood movement on a solid box? some of the stones are ceramic stones and others the dual-stones and a set of diamond plates... all used with slightly soapy water, so I would think a frame and panel would be more stable that a solid piece? I'll be using mahogany for most of them.
