I found the tutorial for this here ( http://www.imperfecthomemaking.com/2012/01/tutorial-hooded-car-seat-blankies.html# ) it's been modified for my purpose :) great looking blanket and very easy to make (depending on what materials you use :) )
This one was made for my sister in law who's due very soon (middle of winter) so this was the perfect present for keeping bubs nice and warm :)
