As I said before, I tried to first stencil on poster board that I cut to fit the backs of her shelf. Whenever I finished, the result was way too pink.
I couldn't let all that time and effort go to waste. We had a big, blank wall in her room, beside where I put the book shelf. I trimmed down the painted poster board and popped it in some frames with mats. I also printed off some clipart from the computer to go with it. I really like the results, don't you?
