This is what I came up with...not all my ideas . I do not have a blank wall large enough to be only used as a design wall nor do I want it left up all the time so....I used the hooks made by 3M that are removeable without leaving any marks , some binder clips and the back of a vinyl tablecloth and placed it on the outside of my sliding closet door. I can put it up quickly and take it down as I want. I leave the 3M hooks up but remove all the rest. Pieces stick to the back of the tablecloth just fine. In fact I have had pieces up now for over 2 weeks and nothing has fallen off. Probably the least expensive method around.
