Hi. I am very new to modding. I actually started 3 days ago. But i followed a tutorial i downloaded from here and learned to make a lightsaber model. however, when it came time to make a texture for it, i had no idea what to do. in the tutorial, it says to take a screen shot and paste into your favorite photo editing/paint program and make your own texture. however i have no idea what it is talking about. could you please tell exactly how to make a texture and what im supposed to take a screenshot of?

Thank you for any help,
Aiwha
