Just us gals (me, Sis and our daughters)
We spend alot of money to go sit in the woods
the hybrid tents have vinyl tops and front windows but canvas side windows, so two different materials
short term for either I would use is Gorilla Tape, but longer term I would use a vinyl glue and a vinyl patch such as used with a vinyl pool
As far as canvas, I believe there may still be iron on patches available, such as the type that my mother used on my jeans when II was a kid.
I just searched amazon for both and both had numerous responses wiwth a product called Tear-Aid being mentioned.
Hope this helps you out
