This yummy fibre is made from milk, pretty incredible really.
It's called Latte.
(More about it if you are interested, here)
It's in the dypeot with some silk. This was an afterbath of some bright pink yarn I dyed.
And here it is naked, as it were.
When I was a kid at primary school in the UK we had a free milk programme, as per the 1946 School Milk Act and were FORCED to drink 1/3 of a pint each day. I hated it and have never liked to drink milk since.
