It was far too late to return them by the time my aunt placed them on her bed, so I hoped for the best. When I took them out of the package, I noticed some loose threads at the seam ends, which made me nervous. I told her to use the gentle cycle and tumble dry low because I wasn't sure how they would hold up to repeated washings. She appears to be pleased with them, stating that they are very soft and cozy, but the top sheet slides around and off of her. Perhaps more washings will make them less slinky. So far, so good; I'll return and edit if there are any issues.
