Teardrops n Tiny Travel Trailers

I see where one guy when he put on the weather seal ran it all around excluding the hinge side. Then he ran a piece on the hinge side and ticked it in the top and bottom seal and he was happy. How come a person can't run the weather trim all around and when he got to the hinge side twist it and continue to meet the other edge?

Sounds possable if you have a soft enough seal. I just cut a peice for each of the four sides and have the ends meet.
