Dear experienced friends,
For the sack of trying something new, I applied a thin layer of Linseed oil mixed with Turpentine on the hard surface canvas panel board. This I tried for the first time. Somehow the layer remains wet and can not proceed to add more details to my work. Any idea how long it would take to dry? Or this is not the way to apply a layer in the first place?
I don't mind wiping out completely and tray all over again...though I hate to loose wonderful expression I got on this portrait. 
I would appreciate your response.
