Hello, I am getting ready to install a Nantucket Beadboard product on our walls. This stuff is 3/8" thick, it is actually a v-groove 6" apart, 4x8 sheets. I have never used this stuff before so I am wondering about the seams. It would be nice if it had a toungue and groove on the edges of the sheet. I assume that the seem will land in one of the v-grooves though. If not, how could I hide the seams Any advice would be appreciated.
