I lied!! I have over 20 colors! Punch Yarn was a big thing some 35 years ago. A search for "Pretty Punch" may turn it up. I score 20 some 250 yard spools of it a few years back.
It is a 3 strand yarn and can be unraveled to use just one or 2 strands for small fly's.
I put it on empty spools and use it in a bobbin.
