Hi, I just wanted to say that Comic Geek helped me with this one and you should check out his Instructables.
If you don't finish an instructable you can click save and exit without publishing it. Then when you want to finish it just go to your regular published instructables page and on the white with orange words on it just above your instructables and click unpublished, that is a similar page but contains your saved unpublished instructables.
