Fold a fitted sheet by folding in half & tucking the corners into eachother. Fold in half the other way so all four corners neatly tucked into eachother, & the rest is folded normally. Then fold as you would any other sheet. Look on you tube, I'm sure someone has done a video of it
Fold everything and put into one of the pillowcases so a complete bed set comes out at once from the cupboard.
