I just finished 2 small bookcases for my woodworking books, made of pine. I want a country look to these and want a milk paint type finish. I want the grain to show, but want color on these bookcases. My father has made lots of pine pieces(bookcases,footstools,benches) and used latex paint thinned 50/50 with water. Has anyone used the 50/50 latex/water technique? Any tips?
