Matt, quick question, i really really like this trick it looks great, but i have a few concerns. I can think of a few ways to accomplish this same effect already, an i'm hoping that they are not the true answer to this.
If you have come up with a method to acomplish the same thing and are happy with it, then stick to that and enjoy it.
Keep in mind, Power Word: Fall is a principle that has 6 variations taught on the DVD. It has not had one bad review in all the copies sold, so it is a powerful and effective trick.
The DVD is well made and the variations taught one by one, so it may be beneficial to you no matter what method you use now.
The items can run out, but should last a while. When they need to be replaced, it is not expensive. You can always contact me telling me the password Paper Crane gave you to the scret webpage, and I will send you to the website where I have found this for the cheapest price. Hope this helps and ave fun! -Matt Sconce
