I have pictures of 5 of our dogs wearing the same sweater that I want to scrap, and I want fuzzy letters for the title. I have some great adhesive ones, but they're white, and I'm planning on using a white backgroud to make the colours in the sweater stand out. How can I add colour to my letters to make them show up on my background? One idea I had is to outline them with yarn, but I'd love to hear some other suggestions! TIA!
