I’m getting ready to start a new bag and it calls for 2 strands of yarn to be held together throughout. I have two hanks from different dye lots, but they look the same to me. The blue part (this color) is on the top and bottom, but I’m not sure that it’s half and half. Would you advise to use one strand from each for the double strand or try to do the bottom with one and the top with the other. (It’s red & white stripes in between- flag theme!) I’m afraid if I run out, you’ll be able to see the difference in dye lots on the top where I changed. But, I don’t know how it would look to have different shades stranded together.
