They're simple, which I like.
Garry's Mod Letters Icons
This is a letter set I created before I had the Icon editor. I made it as an image, but eventually I forgot I had this set. I just converted them to icons, and saved them.
They're based on the Garry's Mod icon, but it looks a bit different because I added some bevel. In my opinion it made it look a bit better.
If you like to play Garry's Mod on Steam with me, add: Dave_The_Gamer
Enjoy these icons!
