Twin size medium blue chambray duvet cover from Pottery Barn Kids. Not just for kids, though, as the color-way makes a great background for many decor styles and themes in a guest room, as well. I have 2 identical duvet covers that are being sold separately.
***Discount of 20% offered if you purchase both duvet covers, plus combined shipping.***
Smoke-free environment; fast and careful shipping.
Thanks for looking!
