You know how when you pick up yarn for a project, the packaging warns to buy enough to finish the project.
That's really pretty good advice.
Especially if you're going to put the project off so long, that the brand of green yarn you bought no longer exists. And you desperately need more.
I found a pretty good match though. Only a person with perfect color vision - someone who can differentiate between any hue would be able to tell the difference.
Oh - and did I mention, my husband can do that - differentiate between any hue. He's been tested.
And the blanket is for him.
