6 is not normal, nor is 8. I think you can get at least 12 from a bag. The chocolate must be runny, which Wilton candy melts is not. It is thick and hard to work with. If you add shortening, It will help but not much. And if you keep reheating you are probably overheating it which will thicken it.Add Paramount crystals to thin it out. Better yet, use a better quality melt such as Merkins. I never have a problem with that.
