Wing repair Thread

[Rookie]

What do folks recommend for the "RIGHT" type of thread to use to oversew the patch tape on a wing?
And is it the same for a bladder surface vs canopy or is a second type needed?

And of course, any suggestions on where to buy?

I'm looking to buy some and have it available...of course following the great philosopher (Murphy's) rule that if I have it I won't need it ;)

Thanks!
Mike
