For a temporary fabric wall try this solution used by Service wives who have to move a lot. Soak sheets in liquid starch and wring out then use a squeegee to paste them on the wall. It will stick and dry. When you want to move and take it with you just loosen and edge and peel off.
I've never tried this myself, just going on what I remember that they told me when I worked in a fabric store in the 80's. Would like to see some handy hints about it from someone who has done it.
