right now, we are living in a rental, so the piano serves as the "mantle" (but without the ginger pots, as they are large and no room). But when we return to our home in _ (hopefully soon), I'll set up the same arrangement as before we moved to the temp rental:
large supposedly 19thC mirror with carved frame above it; fills most of wall except for a few inches around.
on mantle, cream colored porcelain ginger pots on each end. pair of tall crystal candlestick holders to the left of left ginger pot at very end.
In the middle, 3 or 4 crystal vases, one of which was a gift. The others I got from a factory when we lived in Europe. I like that the vases have some color in the glass and how sunlight reflects off of them. Like to keep the vases filled, as they reflect nicely in the mirror.
