Ring this one up as a gift for both of you (and you can never have too many opportunities to work those in). Smooth, cool, silky satin sheets blow cotton away by any reasonable standard. After a long day of reminiscing about all the great years you’ve spent together, this is the stuff that you’ll want to come home and writhe around in. The only problem is you’ll want to stay in bed all day. Better cross a couple of weeks off your calendar just to be safe.
