I have one that my MIL made for Louis, it just isn't as big as that one! I think you'd be surprised how you would go, it as all straigh sewing and her instructions are really clear. Why dont' you make one puff out of any old material / old dress whatever and see if you think you can manage it? You were worrying about what to do for hte next 5 weeks, this may be your answer!!
I love that you are starting to be tempted to be crafty since you have been using the Tree @clothsister !!
