Stackable Christmas Tree with Detachable Flowers

I like my Creeper Christmas tree, but I thought it would be fun to create nonspecific tree. This is what I came up with. I decided to give each layer pegs instead of having a hole go down the center with a stick that goes through it.

Is made up of a stump + 7 layers. Top has a star shape that can be used for hanging. Pieces need to be glued together to hang on the tree as an ornament. Flowers do not have to be glued on. They should fit on snuggly and be able to take them off even with the layers glued together.
