I love the Peppermint Swirl Dress, and I’ve made a few of them for Anya. The 5-year-old size easily fit within four yards of fabric — two yards of each colour. The 8-year-old size fit easily in six yards of fabric — three yards of each color (and about a half-yard of one color was left over, the half-yard from the other was used for the top of the dress). I think the 10-year-old size will be tight with six yards of fabric … but it’ll be a few years before I know for certain 🙂
