Turn the fireplace mantel into a focal point using color. You can hang different-colored stocking or you can display an array of floral ornaments, also featuring a rainbow of colors. You can even borrow a few ornaments from your Christmas tree and display them on the mantel in a creative way. You can use candles to decorate the mantel and make it glow. Use candles of different shapes and sizes and votives and arrange them as you find it fit. You can also use a few other things in between, like pine cones, Christmas tree branches, tree ornaments, etc.

There is also not the burden of worrying if a table is sturdy enough to support the decoration.
