First, make a 11×7 sandstone floor. Next, go to each corner of the sandstone floor and place 1 block of polished granite. To follow that, go one block diagonal from the block in the corners. Then go one block diagonal to the 2nd block in the corners and put 1 block of polished granite.
Then after that put two blocks of polished granite next to the third diagonal block. That should now be on both sides of the court. Then in the middle block of the red cemi-circle put three fences on top of each other. Next put a block of snow on top of the three fences.
Then, place another block of snow to the right of the snow block, and also another block of snow to the left of the snow block. Finally, make another row of snow on top of the first row and add a cob web on the middle block of the bottom row of snow. Also do this on the other side of the court.
