Here is a pine that isn't dressed or finished. This type of material is commonly used for things like studs or noggins. You can tell it isn’t dressed by feeling the roughness of the material and noticing the knots in the wood. When using this timber you have to consider where to place the knots as they are the obvious imperfections in the material.!
