I like the sanded-down look of my oak chest of drawers and I intend to add a few small stencils on the front in waterbased eggshell. I'm wondering if I need to seal the wood somehow after? I don't want to varnish it again as varnish yellows and darkens the grain. But I'm not sure about waxing either. I assume if I just leave it untreated then the wood will eventually show marks from my fingers etc? What should I do to keep the overall look as pale and bleached as possible?
