Being in Alaska for 30+ years was a solution for the stubble. It never got warm enough where I lived to wear shorts so I just never bothered to shave except for the times where we would be in a hotel with a swimming pool! Leg hair stubble isn't a bother under levis for the most part anyway or maybe it's just that one week's worth of growth where is finally lays down and doesn't itch.
In Idaho I wear shorts, capris or a skirt at least 6-7 months of the year so it was a daily thing to shave. For some reason it appears that my leg hairs gave up the ghost this year...a few black hairs right around my knees and a few white ones here and there. It is a blessing since I can hardly find the razor in the shower these days without glasses...let alone the leg hairs! And I don't necessarily feel the stubble? It only took about 65 years for that to happen, so don't despair ladies...live long enough and it might happen to you too.
Well, I do have fewer leg hairs, but they still bother me and as you say, I've been shaving blind for a long time. I shave by feel, but the hairs are so fine (they should be wiry at my age, right, but they are not) the razor often misses them, even with 2 or 3 passes. At least I don't get those nicks and cuts anymore, so I'm happy about that.
Half the time I don't bother shaving because it seems so futile. Right now I'm headed out to do some shopping in my capri pants and 1/4 inch stubble. If anyone even looks at these old-lady legs and sees the stubble, more power to them, I say.
