Picture yourself throwing open a bedroom window on a summer’s day, birdsong in the air. You unfurl a billowy sheet that settles slowly, casually, onto the surface of the bed. You are unconcerned with time, unburdened by stress. The days are long, and the sheet has the lightly rumpled, fresh look of something that just came off a clothesline in the sun.This sheet isn’t like your cotton ones, all tightly woven, smooth, and purposeful. This sheet has a weave you can almost see through, with lines, texture, and character you can feel on your skin. It’s old-school, breezy, maybe even vaguely European.Welcome to the world of linen sheets.Linen sheets aren’t the everyday, practical sheets you build your bedding foundation on. They can be an ephemeral, even mercurial, choice — they’re prone to tears, they’re abrasive (to some), and they can cost an absolute fortune.But a good many of us love them anyway. They’re a lifestyle choice for those who want the summer vibes and evocative mood they bring to a room.For these folks, we recommend six beautiful, breathable sets, listed below from least to most expensive.Everything we recommendBreezy and worn in: Target Casaluna 100% Linen Sheet Set.
