Pillowcases have many different kinds of closures, like buttons, ties, or envelopes. They may also have none at all. Depending on the purveyor, pillowcases are either sold separately or in pairs.

If you compare linen vs cotton sheets in terms of breathability, another major difference emerges — linen will keep you much cooler at night because of its longer fibers and, therefore, looser weave. Air can pass through linen more easily, keeping your body cool. Cotton, as previously discussed, can also be perfect for warm sleepers (in the case of percale bedding), but linen definitely has the edge over it.
