I'm sure any kind can be used, but I used what I had on hand. I used: Candy Corn from NG, Candy Apple NG (regular candy apple, not the winter candy apple), and Cotton Candy and Funnel Cake were both from Brighter Scents. There's alot of talk about the bad service from Brighter Scents, though. I bought mine a while back, and never had any problems, until I ordered one time, and didn't get my oils until months later (and then, it was the wrong oils!). Never ordered from them again. You'll have to find a skin safe Funnel Cake. Brighter Scents was the only one I had found, and it was great for B&B. MMS has a good Cotton Candy too, so check them out.
