The Photoline is a simple but effective way of displaying your printed pictures. Photos can be easily added or removed just by pegging them onto string or wire that runs between 2 pieces of timber.
The whole thing can be attached to the wall using 3M picture hanging velcro strips so there's no damage to the wall.
Step 1: Materials, Tools & Planning
Cut 2 identical pieces of timber. Obviously you'll need to think about how many photos you want on each line and how many lines, leaving enough space between photos. This would be the best time to do any painting or finishing of the timber, although I just left mine raw.
