Hi! I'm curious is anyone knows of an online place I can buy premade buttercream frosting flowers? Like the ones on birthday cake... 

Would a local bakery make these for me or just think I'm weird?... 

I'm not sure you'll find buttercream flowers by mail order...maybe locally...because they are too fragile.  However, ROYAL ICING flowers such as roses, etc., are readily available.  I've seen lots of them on Etsy.  Just go to http://www.Etsy.com and search royal icing flowers.

My fav for royal icing and gumpaste flowers is avalon deco .com  I'm not aware of bc flowers being shipped.

Global Sugar Arts makes beautiful gumpaste flowers.  Yeah, for buttercream you'd probably have to ask a local bakery.
