Wash in cold water or warm, 30° Celsius max.
No bleach, no tumble dry. Dry flat.
I was expecting a close, fine weave like a lawn, but this uses slightly coarser threads woven a little more loosely. It's got a crisp feel that I think will work great for giving volume to a puff-sleeve dress, and the loose weave will make it great for wearing in hot weather. The depth of colors are stunning in person, and didn't fade at all in the wash. Beautiful, beautiful fabric.
