To properly care for plant dyed textiles, wash on cold separately + hang to dry in a shady spot.
The natural (un-dyed) portion of the sun quilt will become deliciously creamy when washed. Which, swoon. But if you want the natural to stay crisp, crisp, crisp -- we get it! -- take your dūnzy over to your friendly neighborhood dry cleaner. If you have access to a green or organic cleaner, even better.
Colors will fade if left in the sun, but we do love a bit of sun fade.
