How to Frame a Collage Poster
- 1). Measure the length and width of your collage poster using a tape measure. Purchase a ready-made poster frame from a craft store that is the same size as your poster.
- 2). Remove the frame's cardboard backing.
- 3). Clean the front and back of the frame's glass using a glass cleaner and a piece of cloth.
- 4). Insert your collage poster into the frame, then place the cardboard backing back into the frame. You can now hang the poster.
