I've had Christmas trees since 1963. My first trees mirrored those I had known growing up. Eventually, I established my own traditions -- each year embellishing and amending according to circumstances and finances. After about 50 years, I realized that I had accumulated too many ornaments/traditions and began giving them away, getting (relatively) smaller trees.
About five years ago the woman who published my first book, Tree Lines; A Memoir, came to my house for a holiday celebration. I'm pretty sure it was she who gave me the ornament saying, "Everyone should have a crystal pig."
Still for me, Christmas is a time to accumulate and share all possible forms of light . . and crystal pigs sparkle.
They also make the days sparkle. It's fun to challenge younger visitors to find the crystal pig. Sometimes they move the critter and challenge me to find her.
