Hey Allaround,
I've got bracket sheets for running a double elimination tournament for anywhere from 3 to 20 players. They're super easy to use. When I owned a bar and did tournaments I rarely had more than a dozen players. How I did it was. Once the sign up was done, I'd pull out the appropriate sheet for the number of players that signed up. Each player signed in on a hand written numbered sheet (legal pad). I'd use a pill bottle with an equal number of pills (balls) in the bottle to the number of players. I'd shake the bottle and pull a pill out. Whoever's name was next to the corresponding number on the sign in sheet got written down on the bracket from top to bottom. It eliminated the possibility of anyone saying "How come I have to play so and so first". It was completely fair and impartial and I never had anyone question or complain about the way I ran the tournaments. The brackets are printable on regular 8.5x11 paper. I think some of the bigger ones may require 2 sheets. If you're interested shoot me your email in a PM and I'll send them to you as an attachment.
