I was just giving you a hard time.

They are called Pinecones. I figured that is what you meant. If you don't mind, where do you live and what is your native tongue?
If this method works for you then by all means, use it. There are a lot of tricks people use that others think are kooky. I would just make sure you keep the heat low. I would not want to clean up melted plastic from the inside of my dryer and clothes. If you can save up the money, buy a clothes detergent for hunting. They do not have scent or dyes in them which may give you away in the woods.
I would agree with your last guess also. I prefer no scent because I do not know where I will be hunting from one day to the next but if you only have one area, continue what you are doing.
