I don't know if this is the right forum... I just take my chances and present my problem ...
On the wall of my son's bedroom we are planning a picture wall of my own developed B&W prints. We have the intention to use the complete wall for this, the size being appr. 20 x 30 ft. The pictures have formats ranging from postcard size up to A3. What is the best way to attach these pictures to the wall without framing them, the underground of the wall is painted plaster
Thanks in advance
