I went Google image searching for a cat silhouette, hoping to find one that was not only cute, but also free to use, so I could share it with you. I sure got what I was looking for when I found this one on Little Scraps of Heaven Design.
I used the method from this post to enlarge the image on my screen to 250%. Then I traced it onto paper, so I could modify the tail. I wanted to make it an S-shape for Boy's name. (If you ask him what S stands for he will say, "S is for snake and BOY!" Pretty funny...anyway...)
