Place your TaleTile between the two wall sections and fit it together to make a solid wall. This then slides into the floor
Slide the walls in and push down firmly to ensure they are held in the floor. The first time you add the walls it may feel slightly stiff.
Add on the corner posts to protect the box structure and help us secure the Lid. If it feels too tight, flip the hole and try the other side.
Pop the Lid over the four corners and show off your completed TaleStack
