The appeal of this garment is universal. It's easy, fast, and fun to knit. Making the sheep textured is an irresistible giggle (and a joy for the baby, too; who needs Pat the Bunny when you're wearing it?).
Finlay writes a carefully detailed drop-shoulder pattern, with separate instructions for shaping the left and right fronts, and simple instructions for buttonholes on either the boy or girl side. You'll be knitting from this for years with different colours and textures.
