The pattern called for ribbon, but I guess I thought it was a bit old fashioned besides I used a "hipper" yarn than the pattern. I just loved the little winter buttons so much and thought they would look cute. The fuzziness of this sweater makes it hard for them to be seen even though they are partially colored. I am sure my dil will like it anyway. It gives her a couple sweaters for the baby when he's older since he will be born in June.
