Buying off-shelf photo frames may be expensive and for large size like poster sized or custom sized it might be a little difficult. Nothing stopped Jacky PhotoGraphies from making their own low cost, functional poster frames.
These can be used to pin up photos, creative calendars, as a notice board and etc…
Main material used : polystyrene board.
Just cut them up to the sizes you need and paint it with a dark colour, black as shown here as a background. You can have it a little crude, the results are artistic and looked a little like graphite.
Here it is, done! Looked like a slap of rough concrete slab.
Stick your poster on it and hang it up!
Job done! Happy DIYing!
Thanks again to Jacky PhotoGraphies for his wonderful article!
