Lighted Trees are no longer just for Christmas! People are using small artificial trees dressed with white lights as a base and are changing the ornaments to suit different holidays.
Although I'm sure a lot of people already started doing this, I never saw one before visiting my fiance's Aunt and Uncle. They had a beautiful "Easter" tree set up in the living room (see pictures) with ornaments of eggs, easter candies, and timeless (i.e. not just Christmas) ornaments like clear icicles and even added lights for more specific flair (i.e. St. Patty's Day green lights with the white lights).
The initial shock of seeing something so beautiful and perfect for the Easter holiday was pure joy. Using ribbons of pastel colors, white lights, egg shaped ornaments made of crystal, plastic, and even wood adorned it.
Below the tree the appropriate holiday "treats" would go. For easter you see easter baskets, For Mother's/Father's Day you see their gifts, and so on. Most holidays and events have some sort of candy assoicated with it, but you can hang anything that speaks to you!
