I was ironing today, and I realised that I have at least four completely different sizes of bedroom pillow case. British pillows are small and oblong, Bosnian ones are usually square, French ones are either large and square or long and thin (like bolsters), and US ones are large and not quite square. I have pillows and cases of all types, gathered as I moved around the world. I am forever putting large pillows into small cases or vice versa, and matching up my bedding is a nightmare. Am I unique, or does anyone else have this problem? And more to the point, why are bed pillows so different in different countries?
