We are using a 12x12 piece of Crinkle cardstock for our box top.  On the wrong side of the cardstock, place the ruler diagonally on opposite corners, and lightly draw a pencil line between them. Repeat for the other two corners. An "x" will result from connecting opposite corners with the pencil.

    With the tip of one corner touch center of the "x" and use a bone folder to crease fold, unfold and repeat with other three corners.

     With the tip of one corner touch the newly made crease line directly opposite, crease with bone folder, unfold and repeat with other three corners.  

    With the tip of one corner touch the first (closest) crease line, crease with bone folder, unfold and repeat with three other corners.

Using scissors make four cuts on the creases as shown. Cut the lines that are one crease line to the right of the center pencil line and one crease line to the left of the pencil line. Cut only one side and then turn to the opposite side and cut again.   Do not cut into the center square that forms the bottom or top of the box.

 When your box looks like the illustration  above you are ready to start folding.

 Fold the pointed tip of one "triangular-shaped" side   down. Fold again. Fold the triangular tabs in, and stand the card up.  

Repeat on opposite side. Fold the “legs” in to make the side of the box. Repeat for the opposite side.

    To make the box shape, fold one of the other sides up and over the first two sides. Repeat for the other side.   

         To make the bottom of the box, trim your cardstock to 11.5” x 11.5”  repeat the above steps.  Draw pencil lines on wrong side of cardstock, fold the box bottom as before, and cut in the same way. To assemble the bottom, cut and fold as we did for the box top.

     You can make boxes of all sizes!  Start with any size square.  The bottom of the box must be slightly smaller, but still in square.  With a 12x12 the bottom should be ½” smaller.  However on a 6x6, ¼” smaller would be appropriate.  Sometimes the thickness of the paper will determine the size.  Experiment – therein lies the FUN!
