Query: blue flannel sheets

I purchased these for my son who lives in Alaska, has a Cal king bed and 18 inch mattress. He called and said ,"Mom, you hit a home run with these sheets". They are deep enough for the mattress, and the softness was great. He loved the fact that he received them in 4 days.He kept the name of the sheets so he could order more, both flannel and cotton. Thanks, people, you made my son happy and made me look good. Not bad for a day's work!
