I found an old afghan pattern that has multi-colored borders with solid color seed stitch between them. You are supposed to use 2 strands of sport weight yarn held together.
There are 4 different colors in the border and the colors change often enough that you can carry the yarn up. But I just can't imaging keeping double strands of 4 different colors from getting hopelessly tangled.
So - my question is: as long as I match the gauge, shouldn't I be able to use a single strand of worsted?
Or does anyone have any other suggestions? Thanks!
