I finally bought a sheet for my bed.  A sheet—nothing more—because this one piece of fabric cost $50.  I don’t understand why bedding is so expensive here.  I would suggest to anyone coming to Korea to find out if their bed will be sheeted and blanketed, and if not, to find out the size and bring sheets of your own.  Not only is everything expensive, most of it is really ugly, too.  Luckily I found a decent looking sheet, and will have to go back to get a matching overpriced blanket.  So dumb.
