Hi, Need some help with the design for my daughter's car (pinewood derby race at our church). I'm a newbie. She's making it so that there is a bird nest on top with a mama and baby birds in it. She wants the car itself to look like a tree branch. I am wondering if anyone might be able to help me as far as what I could use to make the outside of it look like tree bark or a branch on a tree. I'd just paint it brown, but she wants it to look like its textured like real bark. I thought about finding real bark, but I think that might make it to bulky on the sides. Any thoughts? Thanks for your help.
