All we need is the mirror, an empty box, some paper to decorate, scissors, glue stick and some strong glue. I had these silver-gold-black wrapping paper and fortunately I found silver, gold and black craft papers. :-) This looks modern for me. Don't you think?
Of course you can use other colored papers what you like.
Here is video tutorial you can watch how to prepare :-)
Good luck to all of you!
