*To make the T's: Cut a hole in 8 of the pieces on the side of the piece as picture 2 illustrates.
* Cut 24 of the 32 pieces in the place indicated in picture 3. Do NOT cut the pieces through all the way to the 2nd wall.
* The last pieces to be fabricated are the rest of the four ways (that should be 8). They DO need to be cut all the way through.
