DIY modern perforated christmas trees: uses simple paper mache cones found at the craft store, drill a few holes (sand them a bit as needed) and spray paint white. Set a LED tealight (battery operated) under the cone for the lit up effect!
Quick centerpiece: Arrange ornaments in a square vase. Tie a bow around the vase and display on a silver tray, blanketed with artificial snow and+a few extra ornaments. Coordinate the color of the ornaments with your table and holiday decor.
Christmas Table Decoration -Tealight Candle Glasses - these look very festive! I'd have to DIY the tealight holders, but not difficult - I may need to shop for some extra wine glasses at thrift stores - also examples for other holidays/themes
