The problem with the Homedepot and Lowes is even if looks straight in the store a couple weeks later in your shop it isn't.
If I'm making something like corn hole boards they are fine, but if I am making furniture I only go a company that sells quality wood (only one in the area near me), costs more but worth it
Why would you use construction grade lumber to build furniture? Lowes/Home Depot here has some hardwoods, but they are very expensive.
Looks like the original poster is long gone, but this thread keeps living.
Why would you use construction grade lumber to build furniture? [...]
Because it is cheap and readily available. Some people don't know better, and others have tight budgets.
I watched a neighbor build a set of furniture in an afternoon. He made a dining table and two benches, a TV stand with shelves, a bookcase, and a coffee table. All of it was built from cheap contraction lumber. He used 2x4s, 2x6s, and 4x4s. He assembled the furniture with Kreg pocket screws and no glue. He did not use plans, and he barely touched the tape measure, mostly cutting to match and cutting to fit.
It wasn't pretty, but it was sturdy and functional. I left before his wife painted the furniture. It was ready by the next morning. All of it was appallingly crude, but it gave his daughter a quick start when she decided to move out to an apartment with no warning.
