Query: A great idea gone awry...

When I bought these two years ago for my daughter, they were the best sheets! Thickly padded and washed and dried like a dream. I still have them and use then regularly. THEN, when my son came along this year, I got two more. WHAT JUNK! They are now less than half as thick and after only one washing the vinyl backing is all wrinkled. DON'T WASTE YOUR MONEY, they won't last a month of washing.
