Design mini decals by using the design wizard on StickerYou.com. The tool is available for free and works on Internet browsers. Other sites with galleries of design selections include VistaPrint.com and Moo.com.
Visit StickerYou.com and click Create Now to begin designing the decal.
Either upload your own images or use the provided image database to put images on your decal. The website offers both black-and-white and colored images. After the image appears in the editor, scale it by dragging the boxes on the corners. Move an image around by dragging the image itself.
When you're done with the design, click Done Editing, and select a material for your decal. Finalize your project, and order your decal in your choice of format.
