The original model has applied the sewing thread as strings to tied all sticks comes together. The first tie was on the cross frame with two sticks. The second tie added a stick making the first diagonal frame. The third tie added another stick making the second diagonal frame. The final tie was tied up all four sticks for being stronger. It’s pretty hard to tie all come together yet it must require dexterity in every step of tying, and avoiding the situation of the rope loosen.
