Because of the configuration of my studio and the space I have a folding design wall. My studio has a daybed that I can pull out for guests. Of course when I have guests I have to put the sewing machine down and turn the capinet and a few other things. Therefore the need for something more flexible.
If you can always have the design wall up, then go for it. In my case it was first a hanging [an easily rolled up design wall] then a folding design wall.
