From Fedora Project Wiki
After posting to the design-team list some discussion took place. Good ideas were presented by many about using the official logo, logo Guidelines (including MgOpen Modata font), Four Freedom artwork and making the design work for both letter & A4 sizes. A clever new folding design (similar alternative) are a key to this project's success with end users.
I look forward to collaborating with others on a great DIY Sleeve for Fedora.
