Okay, I just posted, and then realized that I am so new that I don't even know the right terminology.
I want to create a design wall that will stand up on its own and can be put up when I am not using it. I have the cardboard, spray adhesive, flannel, and duct tape.
I need to know how big is big enough to be useful but not too big to be awkward. I have seen several here lately that stand up with one fold in the middle, but can't figure out how big they might be.
Does anyone have any suggestions?
