Special materials required: The pattern calls for knit fabric but I have made versions with a woven for the hood. The button placket makes a stretchy neckline unnecessary so you are safe to use a woven at that part. Which brings me to the other special material ... buttons/snaps; you will need two.
So, I decided to make something that can easily be converted to a useful piece for her wardrobe. Not ready for a new purchase I decided on this top and of course, white fleece is the perfect thing to be a sheep. I made some ears and a tail to pin on just for the night.
Bad: I don't have any complaints. It was a nice easy sew with great details.
