How to Display Pictures on a Foam Board
- 1). Cut the foam board down to size using your hobby knife and a straightedge. You can make your board the exact same size as the picture or leave some to serve as a border.
- 2). Trim any extra paper off your image with the hobby knife and straightedge.
- 3). Spray the back of the picture with spray adhesive. Look to create a thin, even coat across the back of the image.
- 4). Align the picture with the board and press down firmly to attach the image. Once the adhesive is dry, you can trim any extra bits of board away if desired.
