One thing I've noticed is that the yarn isn't as worn at either end as it is in the middle – over the first 3 or 4 rows it's still quite soft and springy, it's only around row 8 that it starts to get really twisted and stiffer. I'm not sure why that is, since all of it has been knitted and unravelled in the same way. At the other end as well, it's a little bit less twisted.
I'd like to find some way of also documenting the effects of the process on my body – but because this is a small piece, they're barely visible as callouses or hard skin – more just the soreness I feel when I push the point of the needle with my right index finger.
