I know that there is a simple explanation to this question, but I have been unable to find an answer.
On Terra Trikes, there is a way to attach or mount the safety flag onto the mesh seat back. There is a grommet at the top of the side tube on each side of the seat back. Do I drill through the center of the grommet? Since I don't want to start something and make a mess of it, can someone please tell me how to mount the flag onto the seat back.
