I am just starting my little home based business making cakes and cupcakes and a friend of mine is having a sweet 15 for her niece and she wants to give me the business but she was telling me that they want mini cupcakes and sugar cookies but the theme is vintage so im stuck.. does anyone have any ideas on what and how I can so this? thank you I would really appreciate it I'm new to all this....I love to back but now that i'm doing it as a business I wantmy clients to be happy and satisfied with my product.

Maybe a fun vintage Paris theme?  Black, white, and pink sound pretty good for a 15 year old girl.  Fancy Flours often has some neat vintage cake themed items.

ADo they have invitations you could use as inspiration?

You can never go wrong with flowers. I remember the old type vintage wallpaper with a lot of flowers on it. Also, paisley print used to be pretty neat.  Vintage can cover a lot of things. I am sure the experts who do this for a living can give you a lot of good ideas. Good luck and be sure to post a picture of your final cake. Can't wait to see what you and others come up with!! 

Thanks everyone for your help...I will post some pics of what I end up doing.. thanks again.

thank you!!

No just going by colors right now.

thank you all of you have been lots of help!!
