My Grandmother knitted each of us boys an "Afghan" blanket when we were little. (Over 40 years ago.)
I used mine all through childhood... took it to college with me... took it with me during all my moves across the US... my wife surprised me by packing it along when we moved to NZ. Just this morning, my daughter was using it to get warm before school.
The thing is bomb-proof and still looks brand new.
