hi all, my 1st post here.
just to ask if anyone has tips on displaying photos on the wall to create a mosaic. and at the same ensure that the photos remain reasonably clean and undamaged.
thought of using post-it memo pads but these are too costly (about $18 for one as big as about two A3-sized sheets). i wish to cover a typical hdb room wall from slightly above eye level to the knee level.
