Props for my film!!

In preparation for filming, I am creating props to be used that will fit in well for mise-en-scene to add meaning to my film. For this I am creating a chest with a lock and a key to go with it that the note in my film will be found with. So I've found an old shoe box and I am decorating it to give it a Victorian look so it will fit in with the flashback of the Victorian times. I am making a lock for this box and a key which will both have the symbol on of a butterfly, representing freedom of the two main characters, but also a butterfly is delicate and fragile, representing their vulnerability.
-The butterfly is also half over a sun, which symbolises how they are half cast in light, (i.e they are in a happy and bright and fun life), but the butterfly is of course also half cast in darkness, representing that things could go wrong at any moment.
-This picture of the shoebox is my beginning product for what is going to be transformed into my Victorian chest.
-The note that goes along with my chest needs to look old, so I'm going to use a teabag on the paper to give it a yellowed and old look to it.
