How to tie a knot when double rubber bands are opened?

Double rubber band knot steps are as follows:

1, put two rubber bands directly together, with the left one on top of the right one.

2. The left pull that needs to be positioned in the lower right half passes through the lower right half.

If everything is all right, the next step is to pull the left and right rubber bands to both sides at the same time.

4. This will give the result as shown in the figure, and you can link them together.
