I just found a great little site. It's supposedly only for girls, but I'm sure boys could go there too if they really wanted. I've been trying to find Twilight coloring sheets online for A... despite the fact that she says that she's not one of those girls that goes all mushy over Edward, I suppose.
Anyhow, while looking I found this. It's a great online Twilight coloring sheet. It's kind of like one of those paint applications. You just click on the color and then click on what you'd like to fill in. You can click on the down arrow and get access to more colors, too. Which is a good thing. Because without that, my picture was becoming too brightly-colored to be at all Twilight-ish. I hope you enjoy!
