Another silly little thing, but I needed them so someone else might need them too. If you have wall sconce lights or ceiling light fixtures with a single gang electrical junction box in the wall or ceiling behind them you may find that when you replace them the base of the new fixture (especially round bases) may not cover the corners of the electrical box. If you do, here's a simple fix, a ring that can be painted (or stained if you use wood filament, which is what we did) to go with the new light fixture and cover those visible corners of the electrical box.
