Is it possible to create a completely custom mod through TES CS? Like, if I wanted to add my own visually custom armor to the game (add something that doesn't already exist), could it be done this way, or do I have to learn how to use Blender? There aren't many good, recent tutorials for Blender (that I've found).

If TES CS is only for altering the base game as it is, could someone give me a link to a good Blender guide? It would be much appreciated by this inspired novice.
