Mohair!
2 balls of blue, 1.5 balls of yellow, 1 ball of red and about 1 ball of pink.
The blue and yellow are the only ones with labels, and they're very old and hard to read. The blue is Spinnerin (anyone heard of that? Anyone? Bueller?) "Kitten Soft", which is 57% mohair ans 43% acrylic. The yellow is Spinnerin "Frostlon Petite", which is, this time, 67% mohair and 33% acrylic.
I'm thinking maybe a stripey wrap or something...?
