Never used, washed once in Dropps free & clear detergent I purchased for my son’s new big boy room, but he is a very hot sleeper and it’s pretty warm where we live so he has never, not once, ever used it. I’m bummed because this is cute as all get-out - see close-up photos for the adorable details! Background fabric is chambray, backside is a cute striped fabric Standard twin size - 68”W by 86”L From a smoke-free home Shipped in reused packaging
