I know another graduation card, but this is the season and then it's over for another year.
Silver metallic poster board
Black glitter embossing powder
Cut 4 strips of silver metallic poster board into .5" x 4.25" strips starting at on end glue a silver strip to the black card stock, space 1/2" and glue another until all 4 strips are glued down. Trim off access. Cut the striped piece 1 1/2" from one end to 1 1/2" to the other end creating a diagonal cut. Refer to picture. Line the pieces up on the card stock and draw a thin pencil lines where they end. Remove the striped card stock and stamp and heat emboss the center between the lines. Erase the lines. Glue the striped card stock to the card. Add stars cut out from additional black and silver and add to the front of the card using foam tape.
