If you were 3/4 of the way through a project that is made of Gefrida Cortina - which is 80% wool, and 20% Alpaca - and you didn't have enough yarn?
I'm making the Marsupial Tote in a heathered blue. But the it calls for a color change, which I want to do, and I'm not sure if I have to buy the exact same yarn in order to do it.
Would you use the exact same brand?
Forget about the brand, and make sure that the fiber content is exactly the same?
Felting is felting - so just make sure it's all some kind of wool and not worry too much? Even if it's a little different, it's felted so it won't be noticable anyway...
