Duvets have been in use for long in Germany and in the Netherlands many years before it made its way to England. Paul Rycaut, an English traveler in 1700, was impressed by the duvet, and tried to pass his enthusiasm to his friends. However, it did not become popular in his home country until the 1800s. King size duvets make any bed warm, no matter the cold of winter. Here's a guide to buying one today.

Custom duvet cover
Once you have a king size duvet cover, you can individualise it by making a duvet cover for yourself. The duvet cover can be made from two king sized sheets. The sheets don't necessarily have to match and can be any colour you choose. Sew the sheets together at the sides and at the bottom, leaving a 1/2 inch seam allowance, and leave the top of the cover open. Turn the cover right side our and insert the duvet inside. To close the duvet cover, you can use Velcro, buttons or ties. To secure the duvet inside the cover so that it doesn't move around, you can sew lengths of hem tape inside the corners of the cover and loops on the corners of the duvet itself. While the duvet cover is right side in, thread the hem tape through the loops and tie them. Then turn the cover, with the duvet inside, right side out.
