Finding sheets that fit your bed is generally pretty easy — if you have a queen size bed, you’ll want to buy queen size sheets. Unless you have a non-standard bed, this is basically how it goes.

In 1689, English diplomat, Paul Rycaut visited Hamburg in Germany where he first experienced sleeping under a duvet. He sent his friends back in England some bags of eiderdown with instructions on how to make their own duvets and he also tried to sell the duvets himself. Unfortunately for him, the British people were not keen to embrace this new concept. It was prohibitively expensive, so instead, they opted to carry on using the more affordable sheets and blankets.
