I am in the process of doing a dining room with bead board wainscot. The issue I am having is the wood. I have been to 3 mills. Neither has what I originally wanted: I wanted 1 x 4 x 1/2 lf stain grade pine (I’d even accept a few knots). Mill one: “I’d have to order the blanks, I have 1x6x3/4(yellow) in stock I can give you at $.98 lf. To order it’d be a little more” I generally use this mill, he has good stuff most times, just a little pricey Mill two: “No, I can order the blanks, can’t guarantee no blue stain, it’d be a special order just for you cuz I don’t keep it in. I do have cypress, i’ll let you have at $.52 lf” The cypress was or poor quality, rough finish. Mill three: “I’d have to order the blanks,” yada yada yada I didn’t ask for a price, his in stock boards were inferior, pretty much needed lots of sanding. So, I go to big box to see what they have. Similiar quality of yellow pine, $.72 lf Then I saw this 1 x 4 x 3/8 thin white pine. Sanded, minimal knots, no visible blue stain (it comes in a packaged bundle (from Finland). works out to like $.32 lf if I recall. Thing is, this looks and feels the best. BUT it’s so thin. Dilema is what route to go?? I really have no issues going with the Lowes bundled pack to be honest, but I am unsure how it will do on the wall. It “looks” the best of everything I saw. Nice white, and smooth, I am staining it. But will in buckle, cup, from being thin? Will the tongue and grooves finish out as clean as a thicker board?? Or spend the extra cash on having it milled in yellow and home there is no issues with knots, warped, rough surface etc.
