Cheers. STILL waiting for the tiles to come in stock to finish off the hearth surface. Then a dark hardwood border around that. Happy enough with how I cut the skirting around the fireplace (so it could mount flush to the wall, I didn't fancy cutting the fireplace to go around the skirting).
Trying to replicate the existing skirting using pine board and some parting bead stuck on with a spacer and plenty of caulk.
