For modern ideas on celebrating I check out The Circle Sanctuary I love their site . Here are my 2 fav suggestions.
•Adorn the home with sacred herbs and colors. Decorate your home in Druidic holiday colors red, green, and white. Place holly, ivy, evergreen boughs, and pine cones around your home, especially in areas where socializing takes place. Hang a sprig of mistletoe above a major threshold and leave it there until next Yule as a charm for good luck throughout the year. Have family/household members join together to make or purchase an evergreen wreath. Include holiday herbs in it and then place it on your front door to symbolize the continuity of life and the wheel of the year. If you choose to have a living or a harvested evergreen tree as part of your holiday decorations, call it a Solstice tree and decorate it with Pagan symbols.
•Honor the new solar year with light. Do a Solstice Eve ritual in which you meditate in darkness and then welcome the birth of the sun by lighting candles and singing chants and Pagan carols. If you have a indoor fireplace or an outdoor fire circle, burn an oak log as a Yule log and save a bit to start next year's fire. Decorate the inside and/or outside of your home with electric colored lights. Because of the popularity of five pointed stars as holiday symbols, this is a good time to display a pentagram of blue or white lights.
