I LOVE the 2 strand afghans and have made numerous ones using black as the "dominant" color, along with another color. Some call it the "ugly blanket," but everyone who has received one from me has found that they are very warm, and can stand years of use. I keep one in each vehicle we have, and many times use it for a cover up as we travel, or during my lunch breaks, when I like to read.
A good way to use up your stash also!!
And to use 2 colors for the sports teams. A good afghan for either sex.
I love your colors!!
