I suppose I can always use the excuse 'this is what NOT to do' and leave it at that. In fact I can't believe I'm putting this on my blog. Eeeeeek!!!! Perhaps the answer is to practice, practice, practice. Nah! I won't do this one again, I've learned my lesson.
Moral of the story: When trying a magazine tutorial, read it over and over and over again. Then hand it to someone with more experience and get them to do it, then get them to show you how to do it step by step. Happy crafting.
