Ideally you would use a niddy noddy, which is a simple device to wind a skein on to. Or, if you haven't got one if those, wind it off onto your forearm the same way you would wind rope or a hose pipe. Once you have it in a skein on your arm, ask Mrs Womble to put ties around the skein - 4 will probably do, then slip the skein off your arm and put it to soak in fairly warm water with a little soap added. The soaking will let the fibres relax and set the twist. I usually leave a skein for at least 30 minutes soaking, then rinse, squeeze it out in a towel, thwack it on a wall or work surface, hang it to dry then admire your efforts!
