Ummm... So does anyone know how to stop fitted sheets from slipping off the corners of your bed? It happens to me all. The. Time. It's so annoying and my bed's in a corner, so it's a bit hard to put it back on. Also any tips on stopping the duvet from clumping into a massive lump in the duvet cover?
For the fitted sheet/mattress cover, get an elasticated one (much easier to make sure it doesn't move at all at night). As for the duvet, if you have a end piece to your bed, jam a folded blanket between there and the duvet/duvet cover so that it keeps the duvet from moving about inside whilst you're in bed/asleep. Or simply sort it out when you put new linens on by shaking it into place, then make your bed immediately after waking to ensure your duvet is in its place.
