Well I have been thinking about this for a few days..... I have a baby so I use lots of bounty tissue rolls.... So I used the inner paper roll to make the two towers. Then I warped it with printed tissue paper. For the platform I used a hard piece of paper and then warped with the same tissue paper. Then I used wood glue to put it together. Well.....Wood glue all I had in hand, but it worked perfectly fine.
Cost of this project:
1. Printed tissue paper - $1.00
2. core of Bounty roll - free
3. Hard piece of paper - free
2. Wood Glue - $1.00
