I found the pattern online so I could just post the link, but they only have swedish, norwegian and danish versions, so >.<
And I'm terrible at translating, but it's basically circular needles nr 4 and quite regular yarn (not too thick, not too thin). You start of with 80 stitches and knit first one round, then purl one, then knit one and after that you knit 2, purl 3 all the way around untill the entire thing meassures 12 cm at which point you start increasing as follows:
First increase so that your 3 purled stiches are now four. (for an even result in the end I suggest you increase first at the left side of the cables, then on the right side and so on). After this you continue to increase one purled stich every fourth round four times, and after taht you increase in every 6th round twice (or untill the whole thing is 22 cm long). Then finish as you started- knit one round, purl one, knit one. Finish.
Hope this is somewhat understandable- my english knitting-vocabulary doesn't go beyond "knit" and "purl" I'm afraid >.<
Thanks! This is very helpful... I will make this if I get everyone else's projects done before Christmas. (Socks and hats for the parents, socks for the sister, and socks for the boyfriend.) This will be more motivation for me to get everything else finished!
