Well it does depend on what type of party tu are having. But I do have a few ideas.
One for example is, having pills like in a 'A Study In Pink' as the centerpieces. Another is if your having cupcakes is buying and then purchasing these adorable magdalena toppers and putting them in the cupcake.
link Another is that if tu have tables o something tu could make mesa, tabla cloths out of this fabric (It's his wallpaper)
link Also if you're looking for a más cheaper alternative tu could buy this super adorable cookie cutter and make galletas at your house!
link This is all I could really think of/Find. Hope this helps and isn't too late.
