I have a wedding cake to make and the bride wants gumpaste magnolia flowers on it.  The magnolias on the picture she showed me look like they are only about 3" in diameter.  The only magnolia cutters I can find online look like they all make flowers that are 5"-6" in diameter.  Does anyone know where I can get magnolia cutters for smaller flowers or if some other kind of flower cutters would work to make small flowers that look like magnolias?

I just watched a tutorial on YouTube by HowcastFoodDrink.  Just type in "gumpaste magnolia" and it will be one of the first to come up.  It's a tutorial using small round cutters.  She made a smaller Magnolia- sounds like what you are looking for.  You can usually find something round in your house.  I used an icing tip and a bottle cap- worked great.  Good luck!
