This method for making beds assumes that the sheet has been correctly folded by the laundry. Begin by laying the bottom sheet at the foot of the bed and then fold out the entire length of the sheet. Work with your legs close to the bed and with short and relaxed arm movements. Then check that the sheet has been fitted correctly onto the bed regarding its length and breadth. Then fold out the sheet towards the sides. Then the bottom sheet is folded in under the mattress. If possible, work on your haunches/kneeling with a straight back close to the bed.
