repair worn jeans

[CiderMonkey]

I have a pair of denim jeans that are becoming worn in a few places, the denim is wearing thin. I love them, they fit so nicely, that I'd hate to have to get rid of them. Is there anything I can do to repair them, other than patch them?
Thanks

It's a guess, but here it goes,
turn them inside out and spray them inside out with one of those starch sprays you use for shirts to get them sitting properly, then lightly iron them. You'd need to do this everytime you have washed them.
Also, consider lining the parts that are threadbare with
netting from old trackpants.
