These are very nice sheets.  Yes they were a little rough in the beginning but after about 10 washes they are super soft.  They do not produce linen in the dryer so I know they are of high quality.  They do fit my 16" thick mattress very snug.  Anything over that would be too much.  Overall I am pleased with the purchase.  If you want extra pillowcases they sell those separately but they are too expensive.

Pros: very soft after a few washes
Cons: Not really a con but they are kinda heavy for summertime, great for winter!!!!
