This cocoon pattern is unique in that it has buttons that allow the babe to be placed in it more easily. Especially when they are newborn it can be difficult to get them into one. The diagonal design provides a flap that not only keeps the baby in but keeps the breezes out. It is 17 inches long and could be lengthened for a taller baby. It is particularly good for using with the swing where their feet get cold and it is difficult to wrap them with a regular blanket. This digital pattern contains many helpful photos.
