Today is Palm Sunday for Catholics and Christians world wide. The palms are representative of those crowds in Jerusalem waved when they saw Jesus and his disciples walking towards the temple on his donkey. The day is the start of Holy Week which includes Holy Thursday, Good Friday, Glorious Saturday and Easter Sunday next week. It's the end of the Lenten season and the beginning of ordinary time in the church.
During services palm fronds are handed out. Later the fronds are burned and their ashes are used for the next year's Ash Wednesday.
A neat thing that people like to do with their fronds is contort them into crosses that they keep at their work stations at work, in their kitchens and some use as bookmarks.
Here is a video sharing how to turn your fronds into a cross.
