Scroll of Deception gone wrong

Hi. I never used scroll of deception before and i was so excited when i got one, thought you have to use it on the item you want to change first and then the item you want to make it look like and clicked my equipped item. Without a warning or smth (since its a %0.1 drop i thought there would be some kind of warning message) i got the essence of my equipped item. I didnt use that essence. Is there any way to redo this process? I was so disappointed when it happened to be honest :(
Thanks

There's nothing that can be done. You should've read the thread introducing the transmog: http://forum.warmane.com/showthread....=1#post2743197
There's a .gif in it explaining how to do it.
