This first brush set is comprised of symbols from the refitted NCC-1701 USS Enterprise; Kirk's Enterprise from the movies.
It includes the seal of the United Federation of Planets; two door insignia: Executive Science Officer and Chief Engineer; and 9 departmental logos: Command, Science, Medical, Communications, Engineering, Weapons and Defense, Transporter Systems, Shipboard Systems, and Environmental Engineering.
The actual brushes are black and transparent-no gray background, and there is also no text. Also, the previews shown are at 0.5 scale.
To use these brushes unzip the directory to a folder where you can find them easily. Then find your GIMP folder and the brushes folder inside it. Simply drag & drop the .gbr files into the brushes directory, and then tell GIMP to reload the brushes if it's already open.
This is my first brush set so be nice.
