When to Stop Mending?

This week, yet another pair of jeans has seem to have bitten the dust. This was one of my favorite stretchy denims from the states. 

As you can see, I have spent a lot of time over the years mending the chub rub area of the inner thighs of the jeans, going over the weak spaces with white and blue thread.

Another hole, a rip this time, along the waistband has me considering whether or not it might be time to stop mending and change this pair into something more useful, but I have yet to determine what would be more useful than another pair of stretchy light blue jeans.

Perhaps I'll mend it after all.
