Has anyone found a good way to straighten wire mesh solo?
The grass isn't thick enough to just walk on it and have it bend the
other way. Maybe a big rubber mallet? End of a 2X4?

I've looked on the Internet and can't seem to find anything, somebody
must have found a way to do this without crawling on one's hands and
knees bending it back by hand.

Yes I know I should have bought flat wire to begin with, but I'm
trying not to run out of money.
