I wasn't sure on how to do her skirt at first. But I decided to do a color changing yarn that matched the colors of her skirt (it was also a lot easier than actually sewing plaid on to crochet).
For the picture on her shirt, I went with the Lorax that was on her shirt in the first movie. I love how it turned out! I just free-handed it and was very happy with how it turned out.
Her gasses were another challenge. I wasn't sure if sewing the glasses on directly to her face would work or not. But, they turned out good. Yay! :-)
Margo's hair turned out cute. I wrapped a piece of yarn to cover up where I attached the yarn so it would look nicer.
