I'm knitting a "simple" (ha!) cable and lace shawl The pattern is for dk but I want to do it in my favourate wool which is aran. Although it's lace it is chunky lace, not delicate so I don't think aran will overwhelm it. The design of the shawl means I can reduce the number of repeats quite easily if it gets too big. My question is: how can I work out how much wool I need? Should I just buy the same amount as the pattern recommends in dk? Ta!
