I'll do this one free for us and we'll see where it leads.
If it takes off I can teach everyone who wants how to make them, and they can take the idea to their own block for home games, with the number and location of TWF members, we could easily take over the stadium without having to worry too much about getting official approval.
For those who are interested, a Sword would cost about 20c to make, I usually sell them for a buck, but if you sell them, most of the money goes to an insurance company. I spend more than 20 bucks at the rugby EVERY WEEK, buying a hundred balloons and giving them away is a small price to pay considering that someone is likely to shout me a drink in return for the favour.
