Feathers Pair of Standard Pillowcases Chalk This set of two pillowcases are a must-have for completing (and complementing) the Feathers duvet set. They're super soft, adorned in the same neutral speckled print as the duvet's reverse and will add another layer of detail to your bedding. Joules are proud members of the Better Cotton Initiative (BCI) and are pleased to tell you that this product is made using sustainably sourced cotton.
