I used the Martha Stewart scoreboard with the envelope piece. I used a 10 x10 cardstock. I scored at 4 1/2 on all 4 sides. Then you cut out the triangles, like you would make an envelope. Then you flip the cardstock over and remove the envelope piece, and score at 1 1/2 on all 4 edges. And then fold and turn over and fold again, and just fold everything together clockwise.
