Anyone have non-interlocking bead board seam solutions?

Paint the wall behind the boards black or the color you will paint everything

Thank you!

Not only paint the wall the color of the bead board. Paint the bead board edges the color of the finished bead board.

Good luck!! i'm excited to see yours!

Thank you!

Thank you! I forgot to mention in my query, my handyman had a hart time with the uneven walls so the edges are also unsightly, b4 painting though. I went to Lowe's today & doubled up on the thinnest plastic molding, 1/8" x 1 so the top ends aren't exposed under the chair molding border (he had already put the thicker molding up while I was away which he'll replace the thinner with). There's a baseboard heater on the one side, so instead of using an 1/2 wider, which no one carries anyway, I'm having him put one strip under the railing down to the edge of the baseboard, then meet the seam on the other that will go straight down to the wall. I'm going to try to find an architectural interest to cover that seam at a craft store, having possibly long strands of plastic beads that will resemble architectural detail I just saw as part of a very wide architecturally detailed ceiling molding. I already had the beading in mind, but I was happy to be able to show my handyman what I was talking about since he's not craft-oriented. I'll ask my grandchildren this week how to post a pic of my bathroom on this site. I've never even done it for myself; they're always posted for me by my family on FB! I'd better take a b4 pic now since I'll be away for the weekend when he's going to try to finish the vertical molding & painting.

Auto correct mistake above: instead of using 1/8" thickness but much wider to cover more unsightly mess (neither home store had any other size in the 1/8" thickness anyway. Besides I didn't trust my handyman to have to make a notch by the 2 seams at both edges of the baseboard heater if I had been able to find the wider 1/8"thick.
