Karen knit this cute dress for Gigi from the Swans Island pattern, Schooner Dress. She made the sleeves a bit longer instead of adding pockets, which meant she only needed one skein of each color — and had leftovers (pictured below).
The pattern has instructions ranging between ages 2–10. The gauge calls for sport weight, which means you could use cotton if you’re concerned about sensitive skin (though it’s worth noting that the Swans Island organic yarn didn’t irritate Gigi’s eczema).
