This document provides instructions for using Gimp to create a customized T-shirt design using Robin Wood's avatar templates: 1. Download and open Robin Wood's RSW T-Shirt.psd file template in Gimp. This template contains layers for the shirt design. 2. Create a design by adding text, images, or clip art on new layers. Adjust colors using the Hue-Saturation tool to customize the shirt color. 3. Flatten the image, duplicate it, and remove the background to create a texture. Save and upload the texture into Second Life to display on an avatar.
