We purchased these sheets last Christmas and although the pattern is super cute, they are the worst sheets ever! The material is so thin and cheap.. it's unbelievable really for the price. They are also very slippery and quite small, they are constantly coming loose from the edges of the matress.  The thing however that prompted me to write this review though is the fading. We've now had these sheets for about 10 months and cycle between 2 other sets and the mermaids where my daughter sleeps is completely faded. These sheets are pretty much garbage, so I would highly recommend not buying them.
