GG, I'll cheerfully get to coloring you after I get over the buttered biscuit. That's a oner!
It is double knitting and I found it tedious in the extreme. It's used in the Hoover blanket
which is a lovely baby blanket that is fun to make for it's history, but that's all. I tried holding yarn in both hands and finally settled on two strands held in a specific order in one hand.
