Fireplace surround with design gleaned from local Zillow listings of historic houses in the area. Constructed of southern yellow pine (syp) with mantel brackets of red oak sandwiched between syp for added strength. The mantel is attached to the brackets via a tapered sliding dovetail. The central panel under the mantel is red oak with syp inlay. The molding at the top of the surround was cut with a minimal set of hollow and round planes. The andirons are reproductions of a pair from 1750.
I have a tendency to make a lot of mistakes, so the panels are attached to the wall via screws which are easier to back out than nails. I’m having trouble covering the (albeit relatively discrete) screw holes. I’ve tried some compounds, but the colors don’t look right.
Are plugs of syp the only option?
