To customize the look of your shirt, you need to edit the textures in your preferred image editing software. In this tutorial, you will show you how to use basic GIMP features to make quick changes in the product’s textures.
To get the image files that you will need for editing, see the Making a Shirt tutorial.
Editing the Texture’s Color
STEP 1. Open the textures in GIMP by clicking menu item File ➞ Open and navigating to where you saved the textures from the product page.
To ensure you see everything correctly, check that the texture is set to RGB Mode. To do this, go to the top menu and click on Image ➞ Mode ➞ RGB.
STEP 2. Add a new layer. The easiest way to change the color of this texture is to make a new layer. To do so, look for the toolbar on the right bottom corner of the screen and click the add layer button
A new window opens to set the attributes of the layer. Click OK.
STEP 3. Choose the color you want to add to your texture. Start by setting the foreground color.
Click on the foreground color swatch to bring up the the Color Picker and select a color you would like to use for your shirt. In this tutorial we are going to choose purple.
Once you have decided which color are you going to use for your shirt, click OK.
To fill the layer with the chosen color, select the Bucket Fill Tool on the left toolbar.
Once the Bucket Fill Tool is selected, the shape of the cursor changes. Move the mouse over the shirt and click on it to fill the layer with your selected color.
STEP 4. Change the layer mode to HSL color.
CONGRATULATIONS! The front of your shirt has a new look! Now let’s spice it up a little more by adding text and images!
Adding Images, Text, and Other Design Elements
Let’s add an image!
STEP 1. Select your texture file from File Explorer (Windows) or Finder (Mac), and drag and drop the image you have chosen onto the project in GIMP.
STEP 2. Scale the image by selecting the Scale Tool . It can be found on the left toolbox.
Click and drag the resize handles at the corners of the image to adjust its size.
To adjust the position, drag the center square of the tool. Hit Scale once you’re finished.
STEP 3. Move your image to the position you would like it to appear on your shirt by selecting the Move Tool . It can be found on the left toolbox.
STEP 4. Remove the white background of your image layer by going to Select ➞ By Color and clicking on the white pixels. Tap the Delete button on your keyboard to erase the background.
Let’s add some text!
STEP 1. Add some text by selecting the menu item Tools ➞ Text or by simply clicking the Text Tool and clicking where you want the text to appear. You can then customize the font, size, and color.
STEP 2. Add a gradient to the image layer or text layer or any of your layers!
Start by creating a layer above the layer you want the gradient to appear on.
Next choose your preferred colors by selecting the foreground and background colors using the color picker for each. The Gradient Tool uses the foreground and background colors for the the gradient start and end colors.
Now, click on the Gradient Tool and click-and-drag in in the direction you would like to create your gradient.
Finally, set the layer mode for your gradient layer that achieves the results you desire for your gradient.
