iImage Information

Start with one piece of posterboard. Using the ruler and the pencil, measure and draw a 8.25" x 8.25" square on it. Then, from the bottom right corner of the square, measure in 4.5" towards the middle of the base and mark a dot with the pencil. From the bottom left corner of the square, measure up 4.5" along the edge and mark a dot with the pencil. From the top left corner of the square, measure in 4.5" towards the middle of the top and mark another dot with the pencil. From the top right corner of the square, measure down 4.5" along the edge and mark a final dot with the pencil.
Connect the dots as shown in one of the photos below. This will create a slanted cross pattern.
Use scissors to cut out the square . Then create four pieces by cutting along the remaining lines. The pictures below show all of the necessary dimensions.
