I don't know if you can tell from a photo but these are magic pillow covers. They use the interfacing method (or, the coolest patchwork technique you've ever seen), and you'll have one whipped up on no time flat. That means you'll be outside on your Adirondack chair sipping lemonade before it gets too hot. And that's how it should be, this summer. Hand wash cold and lay flat to dry. Finished size: Large-patch pillow fits an 18" x 18" (46cm x 46cm) pillow form; small-patch pillow fits a 16" x 16"
