i want to crochet a bag with the recycle sign on it, but i don’t know how to go about adding the different color yarn in the round. I know i could add it, and then finish the round, but then the yarn would be trailing out of the left side of the picture, and i would need it on the right. How do i fix that? Do i need to carry the yarn with me through the whole round? and if so, how do i do that?
