I have been knitting a lot of small, quick things lately, and now feel as though I am ready for a bigger project again. I have this beautiful Louisa Harding yarn that I bought on sale back in January, and I am going to knit a sweater with it. The yarn is a variegated angora/wool blend. I have heard that you should alternate between skeins of varigated yarn to avoid pooling- how often do you think I should alternate, and where should I do it- at the beginning of a row? I love this yarn and want to do it justice by making the sweater right!!
