oh so summer-ie
I made one also for my niece for her bday. So beautiful and bright.
Now with the full flower that you took off you might want to cut away some of the plastic(not all of it so the flower is still in connected) this way when you hot glue it is sorta flat in that area and will stay.
With the leaves you might want to add a dab of hot glue right between the handles but not on the metal spring.
