We want to fit some sort of wooden mantelpiece (probably some sort of fairly think reclaimed oak plank) on the rather plain wall above the fireplace recess in our sitting room that has a large woodburner in it. I am intending supporting it with two brackets fashioned from the same piece of wood. I'm trying to think how I could attach it all to the wall fairly invisibly, but have no knowledge of the kinds of fittings or techniques available. Any suggestions?
TIA
