Smell that? It's...it's...BULLSHIT!

Seriously, if you want to look professional, here's what you do. Take a glass bottle and punch a hole in the middle of the bottom. Use a powerdrill or nail file to smooth the hole into a nice circle big enough to fit a couple fingers through. Fill the bottle with dryer sheets kind of loosely. Blow through the neck, no smell but laundry. Then, to replace sheets, just pull them out through the bottom, clean the inside, and replace.

No need to spend 20 bucks when you can have a beer and enjoy making a good looking one yourself.
