I was also really worried about swelling since I had to use pine, so I over compensated a bit on the ends & I also use that extreme flex stuff for the caulks
I just filled the underneath with caulks, I remember that one really stumped me for a while I just sat there & stared at it, couldn't figure out how to do that w/the way the crown molding is at an angle, it was my gf's idea to do that actually but I didn't have any idea what she was talking about at first. It sort of bugs me but still idk how I could have done it differently. It's the inside corner of this though...
So it's fine really, hard to notice unless you're specifically looking for it. That little section there was the hardest one though it took me longer than some of the rooms.
lol I was super tired for some of it bc it was a bit of a rush job while we were paying for two places, I realized later that I could of probably done that with one peice. I just couldn't see it at the time. Plus I was cutting it, holding it up, cutting it, holding up tetc etc trying to get it to fit & by myself.
