I created Blue Square North and South kits since I couldn't find those anywhere and I enjoy playing a non-conference team and bringing them up (hopefully). It's my first go at doing this so be kind.
In attempting to match the FM kits with a real life counterpart, I tried to match the jersey maker, colors, specific design, logo and sponsorship logo. There were a few where I had to guess on the above details due to a team's horrid web site of the good pictures of a team being unavailable on the 'Net. There are at least two created jerseys for each North and South team plus a third jersey for all teams FM 2011 stipulates as having one.
Hopefully you enjoy the pack.
How to install:
Download the .rar archive and use a tool such as 7-zip to extract the folders.
Copy those folders to:
My Documents/Sports Interactive/Football Manager 2011/graphics/pictures/kits
Create folders "graphics", "pictures" and "kits" if they don't exist already.
Run FM 2011, make sure to un-tick "Skin Cache" in Preferences and hit Confirm.
Thanks to Chad on the official SI forums for creating those kits!
