I cannot over-state the importance of careful wood selection. I mentioned earlier that birch ply can be found in three shades – white, yellow and red. I prefer the latter. The difficulty lies in finding a consistent source. For example, I found 1/8″ 4 X 8′ ply (I need two more sheets to finish the ceiling) and 1/4″ to begin the walls at the same high-end lumber yard. Problem was, the two different thicknesses were dramatically different colors. Have a look:
These are two unfinished sections and the color difference is dramatic. I was hoping with a little stain and poly-coat that the difference would brush out – giving me the option of having walls a slightly different but compatible hue than the ceiling. No such luck! Yuck!! The color contrast is even greater once treated and offers no match. I should have known better. This is Crayola 101. You add green stain to red wood and you get brown – green to white you get green. Pretty basic stuff. I guess I learned that in Kindergarten. Buy Carefully!
