First, let me say. Be picky about the lumber you get for tongue and groove. We went through it pretty good and still ended up with a couple of pieces that I wasn't sure were going to work out. Even a slight bow in the wood makes the task MUCH harder. We got through about 20 pieces of the 45 we bought but some of them were work. The other challenge is that you're working over your head. I'm not sure which is worse, holding your arms upright over your head for 3-4 hours at a time or climbing up and down a ladder several hundred times. I'm really hoping we finish the other boards this coming weekend but if we don't, it's OK. We'll work at it as we can. Don't plan on completing any significant work per day without some major aches and pains. :)
That said, I think it's really turning out nice. We had every intention of white washing it when done but now that we've seen it installed, I think we're leaning towards just oiling and sealing it. I love the honey color of pine and the oils will just pull out the depth of the grain.
Here were some pics after a batch of boards went up.
