What is the best way to achieve an open grain finish on a pine board

My wife wants a chest finished with an open grain (not sure if I even have the terminology right). Its pine and she wants it to look aged - sort of like an old weatherboard would appear after years of aging. The idea is to lightly wash it with a white finish (lime?), rubbed off and just leaving a small residue in the surface irregularities. The idea being to make it appear that the chest is an old one that has been painted and most of the old paint has weathered off.



Can anyone tell me how I would achieve that finish from a pine board that has been sanded smooth.



I know it sort of seems I am working backwards trying to make a finished item look unfinished..but that's what she wants
