A suggestion would be to use a dowel glued to the top of back of the paper using acrylic medium. Small flat eye hangers could then screwed into each end of this dowel for hanging purposes.

A similar dowel could also be attached to the bottom back for weighting purposes (so paper doesn’t curl up)

The weight of the dowels would be determined by the gsm and size of paper used in the work.

I suggest a dowel because the round shape would allow distance from the wall.

If you wished to use a lighter paper and wanted the work to perhaps ‘move’ in natural drafts, then instead of a bottom dowel, attach metal or plastic washers on the bottom (at back). Playing with the weight. (Check the hardware store for suitable items).

I would also consider a coat of acrylic medium on the back of the paper for protection. Either regular or Golden makes GAC medium which will stiffen paper. All dry clear.
