Well it does depend on what type of party آپ 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 نہیںملتیں toppers and putting them in the cupcake.
link Another is that if آپ have tables یا something آپ could make میز, جدول cloths out of this fabric (It's his wallpaper)
link Also if you're looking for a مزید cheaper alternative آپ could buy this super adorable cookie cutter and make کوکیز at your house!
link This is all I could really think of/Find. Hope this helps and isn't too late.
