Hi, I'm trying to do a johnni walker black label cake shaped like a bottle but I don't know how to get imaging to put on the cake. Can anybody help me 

If you "google" Johnny Walker Black Label bottle, and click on images, you will see tons of images of the label and the bottle. Find one that you like best (make sure that the file is large enough that when you enlarge it, it stays clear an doesn't "pixelate") and then print the image out onto an edible icing sheet. I used this method to do the Absolut Vodka label in the cake below:

GREAT! Thank you! I will try that! 

@Michele25 Do I order white frosting sheets to do the image?

AYes, creativesweets1. I buy the 8x11" size white frosting sheets and then cut the image out after it's been printed. Good luck! :)

AGreat thanks! Are they all the same? Do you know a website where I could order from?

There are many different brands of frosting sheets available online, and many companies that offer them. There are also MANY threads on this site that give information and recommendations on different brands of frosting sheets, edible ink and printing systems. I personally use, and have great luck with Inkedibles brand icing sheets and edible ink (after using two other brands and experiencing problems). Their website is http://www.inkedibles.com/

Great! thanks for youe help
