Also you could “shingle” them over each other instead of arranging them like tiles on the styrofoam. LOL it’s fun to take these ideas and develop them further.<<<
Good idea.
I would not want glue on candy wrappers and I see no reason to waste the candy, it should be eaten, if it is saved the ants and bugs will find it.
We had ants find and eat our sugar cube village.
And you want the cone to cover with dried flowers.
That's right, when you pull the pins out it won't damage the cone (much) and it will be fine for other projects. Otherwise you'd have to throw it out with candy wrappers hot glued to it.
These ephemeral projects are difficult to store from one year to the next. Like your sugar cube village - too bad! Better to look at them like gingerbread houses, good for one holiday. Make it for one year, enjoy it, and then take it apart for its components and use the pieces for something else.
