I made a set if twins sweaters and hats out of baby cashmerino. They were lovely and the mom says they wear them all the time.
I made an adult sweater out of the chunkier cashmerino, and it pilled horriby after I washed it. I managed to shave most of the pills, but I'm just so disappointed with it that I may do it in a different yarn since it's for my neice.
There are some lovely, inexpensive baby yarns out there. A lot of them contain nylon and the all feel really soft.
