(2) Invoicing: Open the sheets with both hands. Palm down, grab the head of the bed sheet and press it on the mattress about 30cm, then lift the bed sheet to a height of about 70cm, so that air can enter the bulging end of the bed, and lean forward slightly, so that the bed sheet is forcibly thrown out. When the air pushes the tail of the bed sheet away, the bed sheet is pulled to sag in the direction of the bed, and the center line of the bed sheet does not deviate from the center line of the mattress by using the buoyancy of the air, and the drooping parts at both ends are equal. ?
(3) wrap the corner: wrap the bedside first, tuck the drooping sheets under the mattress and wrap the right corner. Pull up the drooping sheets on the right side with your left hand, tuck the sheets on the right corner under the mattress with your right hand, tuck the sheets on the drooping corner at right angles with your left hand, and tuck the sheets on the drooping corner under the mattress with your right hand. The left corner is the same as the right corner, and the left corner at the end of the bed is the same as the left corner of the bed. When wrapping edges and corners, the directions should be consistent, the angles should be equal and tight, and the towel corners should not be exposed.
