My niece and I had just as much fun making this project as we did giving it to her dad for his birthday. She especially loved watching the print develop in the sun! Prior to the tutorial, I asked her to draw a nice picture that we would make into a simple pillow. A baby and daddy dinosaur is what she came up with -- so cute!
All you need for this project is Inkodye, a glass plate (I got mine from a picture frame) and a black Expo marker. I recommend using Expo brand markers specifically because they block sunlight really well (you could also use a transparency instead of a glass plate).
