Bulletin board border, also known as trim, frames the bulletin board and makes it look finished and more professional. Store-bought border comes in a variety of shapes: scalloped, straight-edged and shaped. Although the border typically matches the lettering on the board, it is a matter of preferences. You can make your own border from any stiff paper such as card stock or poster board.
Making the Border
Measure the distance around each side of the bulletin board.
Determine the desired height of the border. Keep in mind that traditional border is normally about 2 1/4 inches tall.
Cut the paper to the appropriate height and length using a straightedge or template. Conserve resources by using one piece of poster board as much as possible, lining up scallops to fit like puzzle pieces, or straight edges side by side. Consider laminating the border for added durability.
Attaching the Border
Place the border along the edge of the board, top side facing the center of the board.
Staple or pin the border, making sure to keep it flat on the board.
Save the border for use in a later board, storing in a flat box. Remove staples neatly to avoid excessive tearing or damage.
Items you will need
Card stock or poster board
Razor blade or scissors
Straight edge or template
Experiment with multi-colored papers for more unusual borders or decorating plain-colored borders with stickers or paint.
Instead of traditional paper border, consider using inexpensive supplies such as raffle tickets, playing cards, or hot-gluing crayons to the board.
Make a cardboard template for complicated shaped or scalloped borders; store the template for later use.
