It's very easy: The yellow starter thread - which comes from inside the yarn skein - marks the beginning of each sock. Simply cut off the yellow starter thread and begin knitting the first sock. After the first sock is completed, unwind the yarn to the next yellow starter thread and cut it off. Then simply knit the second sock. addi CraSy Trio aka Flexi Flips needles are the latest way to knit socks. Using 3 flexible 21cm circular needes brings a new feeling to sock knitting. The needles don't get tangled and you won't drop stitches as the needles won't fall out. * Disclaimer: we do not accept discrepancies in yarn hue as a subject for claims. Almost everybody sees and describes colors differently. The colors are named by the manufacturer, not by us. Our pictures are as accurate as possible. Please keep in mind: yarn color swatches are rendered differently based on your monitor. The best way to be sure you are finding the desired color is to visit your local yarn store.
