The rope arrived today, and I cut it to an appropriate length and tied loop-shaped knots so it can be easily worn. I estimated the distance between each loop — that is, the distance between two people — to be about 150 cm, and cut the rope accordingly, leaving extra length for making the loops. If the distance between people is too short, it could cause discomfort while walking, and if it’s too long, it might be difficult to maintain the spacing or both people might not fit within the frame during filming. Therefore, I chose 150 cm as a reasonable length. The loops were tied in a way that takes into account different body types and allows for easy wearing and removal.
