This ribbed sweater is ideal for the toddler, since there are no buttons, and because its stitch allows it to grow in size along with the child. Make it of five ounces of white (or whatever color you prefer) sport yarn, for a two-to-three-year size. You will need a pair of standard knitting needles number 4, plus three stitch holders (safety pins will . do) and one set of double pointed knitting needles number 3.
