UP + DOWN = 1 / Universal Design

Traditionally, while changing the blanket sheets, one has to flatten the thick and heavy blanket, and simultaneously grasp on to the two corners which connects the sheet and the blanket itself, and flap very hard in order to make the sheets even. this simple move, however, may become difficult for some females and easily slows down the job.
Therefore, I divide the sheet into two layers. all you have to do is stack the sheets up like when you are making a sandwich, and hold the four corners still in the process, it simply reduces up to 2/3 of the strength required.
The buttons can transform into a hook, for the convenience while hanging.
