What to do with your Palms after Palm Sunday?

You are correct in your application of the palms. They are not holy but a reminder to the people of God, that sometimes we are in line with Jesus and adore him. Other times, we turn away and forget that he is Lord and deny his commandments to love and forgive and worship. So after the season keep them and place them in your bible or other book. Another thing to do is burn them outside and if you wish, use the ashes for a plant. Then the plant and you can think about Jesus and his living in you.

I used to be a secretary for the church. Each year the Pastor would collect any left over palms and burn them and use the ashes for Ash Wednesday.

Many members of the church make a Cross out of them and use it as a bookmark for the Bible.

Wet the palms and lay them on the floor in your apartment as a representation of what you want God to do for you.

Hang them behind my Crucifix until the church requests them back to make ashes for ash Wednesday

I do know that ones from the previous year are to be burnt, not just thrown away, as they have been blessed.

I do all kind of things like put them in picture frames

I use them to weave next years Easter baskets!

I go out back behind the barn and use them to choke a chicken.
