I use the "v" and don't have any trouble with the skins. I just bunch them up at the end of the tarp.
This is the way I did it as well but hated the fact my skins would be soaked in the morning with rain or due. Even after toweling off the tarp I would still be putting it in wet snake skins. That's the main reason I switched to the small ties.
Actually I use some of my daughters hair ties/bands.
