Step 1: The materials
1. 2 cardboard boxes (for the sides and the towers)
2. 1 or 2 thinner boxes (for the accesories like the spikes, arched walls, and the round tops)
3. A thing to cut the boxes with like a knife of scissors*
4. Lots of tape or glue
*be very careful with the cutting item. I would recommend wearing gloves for this.
Step 2: Cutting the cardboard
The next step is trickier, but not by that much. Get the next box and cut out one side. Cut the side in half. Each half needs to be rolled up and taped. this is the beginning of the back towers.
The third step involves cutting out two sides. Draw out fourths and cut out three-fourths. remember, cut into three-fourths, not into fourths. Fold them into eight sections and tape it up. These are the main towers.
