Building A Kids Fort Knots Used To Lash Logs Together (FORT BUILDING)?

Knots used to lash logs together (FORT BUILDING)? - building a kids fort

I was curious as to what is needed to make 4 knots records together as a structural basis for a strong? () The square

I built a round thing in a team record in the open air was a kid, I forgot how to build them. Moreover, this knot that I have to use if you want to bind together (in parallel) to the walls.

Thank you!
