We made Christmas trees from old hymn books. I could have never pulled this off if our ward wasn't getting rid of all the hymn books. I think we made 120 trees. The tutorial for the trees is here.
We used lots of popsicle sticks to make stars and mason jars filled with photos of ward members from past Christmases.
I saved the Christmas songs from the hymn books to make little Christmas songbooks. I think most of them ended up in the trash. Oh well.
We also made lots of lollies. These were so easy to make but when you are making 100s that's where it gets time consuming. We called the day we made the lollies - Lolliepalloza. We also had giant lollies on the wall.
The one thing I didn't take pictures of was the luminaries on the stage. To make it I saved cans. Then you put water in them and freeze them. When the water is frozen draw a design (upside down if you aren't using a candle) and use a hammer and nail to make the little holes. We placed the cans on top of a string of Christmas lights.
I thought it turned out pretty cute and everyone loved the little trees and took those home at the end of the night. In case you need some ideas for your party.
