I love these sheets!  The are a lightweight flannel which is nice since I live in Texas and our winters are not that cold but lots of cold nights.  I washed them before I put them on my bed and they came out great.  I also love penguins so this purchase was a win!!  They were a perfect fit on my queen bed and I feel like they will last.  I was so comfy getting into bed that first night.  Really great sheets overall.
