You know what  just downloaded, but in case you are 
new to the magical world of skins, here's how you install it:

move the materials folder that should be in the ZIP folder to:
C:\Program Files\Valve\Steam\SteamApps\"your SteamID goes in these quotations"\counter-strike source\cstrike

Unfortunately, if you are new enough where you need the above 
address, you might have to create folders along the way.
Good luck, and enjoy!
