Just as the question asks: how do I fix my favorite pair of jeans where a couple of the belt loops have pulled away free from the jeans? They're still attached to the jeans by the top of the loop, but now there's a small hole where they've come detached at the bottom of the loop. I've been trying to be diligent about not using them to pull my pants up, but I might have done so without thinking.
I'd like to reattach them. I don't have access to a sewing machine or "spare" pieces of denim.
