I did a quick wash on these sheets before using them. When I took them out of the dryer there was a small hole in one of the pillow cases, which doesn't surprise me as these sheets are very thin & totally not what I expected for "polar fleece". I called Wayfair & Becky was extremely helpful & offered a full refund.
I do NOT recommend this sheet set. 
I will, however, continue to shop Wayfair as they are a stand up company.
