When Jem tells Scout about getting his trousers back, he tells her of something strange. What is this?

Jem tells Scout that he found his pants neatly folded and left hanging over the fence, and that someone had also attempted to mend them. He said that it wasn't like a woman's job of mending, but rather like a man's- uneven stitching, but at least the hole was closed.

He found his pants neatly folded and stitched back together like a man did the stitching, it was bad work and very uneven.
